Unnamed devices can be specified by their specific SES device and element number. This greatly reduces the chance of getting it wrong when you (or the datacenter technician) physically pulls the disk. You can also reboot, and GEOM will pick up the multipath when it first tastes the disks during boot.

Direct Attached deployments require a bit more hardware and cabling. The NVMe interface is also extensible to allow operating over the network (where it is known as NVMe Over Fabric or NVMe-oF). NVMe on the other hand, supports multiple queues (often 64 queues, but the official specification allows for up to 65,536 queues) allowing for many commands to be run concurrently. While both SATA and SAS allow multiple commands to be issued at once to the device, these commands cannot actually be executed concurrently—instead, they are queued for sequential operation.

  • In addition to the above query types, SES also supports a number of commands, including activating the “locate” and “fault” LEDs if present, and the ability to individually power off drives.
  • While I have been aware of this in my home server as well, it is easy to forget to ensure that disks are not silently killing themselves by cycling the heads.
  • An eight lane controller can only directly attach to 8 disks, requiring more controllers (consuming additional PCI-E slots) to connect more drives.
  • My Seagate Exos enterprise drives make almost 0 noise actually.
  • SATA+AHCI improved data transfer speeds, simplicity of communication, and included abilities that we today take for granted, such as “hot swap” and command queueing.
  • The settings you mentioned are already set this way.

My question is – is there a way to tell if a certain disk suffers from the issue prior to purchasing? For the system I’m monitoring here, the SSD that it boots from has a wearout indicator sitting on 95 of 100 (only 5% of the rated life consumed), visibly unchanged for a long time so it’s not very interesting as an example. (The properties like ID_SERIAL_SHORT can be queried on a running system using udevadm info, such as udevadm info /dev/sdd to get the properties of the disk currently assigned ID sdd.) Somewhat more useful for monitoring is the smartmon_load_cycle_count_raw_value, which provides the actual number of load cycles that have been done. Secondly what are your disk monitoring refresh intervals and what do you use on your system to monitor SMART disk health?

How to Convert a Recorded AnyDesk Session in 3 Easy Steps

The timer values specified are in milliseconds, so this example will park the disk heads after 30 minutes of inactivity. If we wanted to allow the disk to still park its heads but at minimum frequency, setting the APM value to 7Fh (hdparm -B 127) seems to be the correct choice. Of the three disks that I decided need some attention, I have one Western Digital disk and two Seagate ones.

Obligatory word of warning – mucking with low-level drive settings like this can cause issues. Has anyone found a tool that can use EPC to change the Idle_b and Idle_c values for Exos drives?

The APM specification dating from 1992 includes some controls for hard drives, allowing a host system to specify the desired performance level of a disk and whether standby is permitted by sending commands to a disk. In addition to the above query types, SES also supports a number of commands, including activating the “locate” and “fault” LEDs if present, and the ability to individually power off drives. The first step is to map out the relationship between the physical chassis where the disks reside, and the logical devices enumerated by the operating system.
Unfortunately, APM settings don’t persist between power cycles so if we wanted to change disk settings with APM they would need to be reapplied on every boot. Advanced power management levels80h and higher do not permit the device to spin down to save power. For example, a device may implement one power management method from 80h to A0h and a higherperformance, higher power consumption method from level A1h to FEh. To prevent parking more often that is useful (for a server, usually that choice would be “very rarely”), there are a couple ways to do it and which apply will depend on what the hard drive vendor’s firmware supports. With the SMART metrics captured by Prometheus, it’s fairly easy to write a query that will show how often a given disk is parking its heads. Since I use Prometheus to capture information on the server’s operation however, I can use that to monitor that my hard drives are doing well.

Other interfaces for remote storage include iSCSI, Fiber-Channel, Infiniband, RoCE, and others, reveryplay but those specialized solutions are beyond the scope of this article. Serial Attached SCSI (SAS) is the most common interface for enterprise storage, first appearing in 2004. Serial ATA (SATA) is the familiar interface used for non-enterprise storage, and is an extension of the original ATA interface dating from the 1980s. In this article we will discuss some strategies and tools to make managing disk arrays on FreeBSD (and related platforms like TrueNAS Core) much easier. It may be what you want is to enable HDD standby, which will “spin down” the drives when not in use
I will optimize settings later for the security/quietness tradeoff however, I’m very pleased with it for now. How can I set this value on the Truenas interface? Keeping it spinning but not accessing data is safer. I would still recommend against idling your drive as that reduces longevity. I also set the tunable vfs.zfs.txg.timeout to a somewhat large value so the regular syncs don’t happen every 5 seconds.
It is fairly well-known among techies that hard drives used in server-like workloads can suffer from poor configuration by default such that they frequently load and unload their heads, which can cause disks to fail much faster than they otherwise would. My Seagate Archive SMR disk (which began life as an external hard drive and was retired from that role when it became too small to hold as much as I wanted to back up to it) apparently doesn’t support reporting EPC settings (since asking for them says so), and initially didn’t accept new values for the idle timers either. The Prometheus Node Exporter is the canonical tool for capturing machine metrics like utilization and hardware information with Prometheus, but it alone does not support probing SMART data from storage drives. While SSDs don’t have any heads to park, most do report a media_wearout_indicator that represents the amount of data written to the device in relation to the amount that it’s specified to accept before the Flash storage medium wears out.

Once you’ve done so, you must test delivery to your “real” inbox—you don’t want to learn that delivery isn’t working after your storage has already become unavailable! If you’d feel safer with a team of experts monitoring your storage, consider a ZFS Support Subscription. If you rely on manually checking on your storage periodically, you will regret it. Another important aspect of managing your storage system is configuring notifications. Klara recommends embedding these details directly into the ZFS vdev properties of each disk—a feature Klara created, which will become generally available in the upcoming OpenZFS 2.2 release. In these configurations, your system may or may not support features like individual “locate” and “fault” LEDs.

Using the no-op true command on other paths to that disk, will cause GEOM to re-”taste” the disk and see the label and automatically add the additional paths to the existing multipath. This will write a GEOM Multipath label to the last sector of the disk. Each SAS Expander will present as a new /dev/ses# device, so your system may have more than one.
Sounds like the drives being woken for the ZIL to flush writes to the ZFS pool and then going back to idle/sleep every 5 seconds. Enable the checkmark for the Syslog and choose a pool that is not based on hard drives. I had this same problem, using HGST data center refurb drives.
I moved the system dataset to the boot pool. I don’t move any data, no apps are running, this is a vanilla Scale install so far, yet the HDD is in constant work. 1 SSD to boot and 1 HDD to store data. Agree, I have used SeaChest with good results for this same issue on scale plus drive cache. If you do it on a live pool, I’d back up your data first.

  • Yeah, it’s not helping, thanks.
  • While SSDs don’t have any heads to park, most do report a media_wearout_indicator that represents the amount of data written to the device in relation to the amount that it’s specified to accept before the Flash storage medium wears out.

  • Whether you are a computer technician in charge of technical support or a student who needs to work together with their classmates, AnyDesk is the program you are looking for.
  • Replacing the drive is financially out of the question.

SATA disks plugged directly into the motherboard use an interface called AHCI which does not provide much in the way of advanced management features. For smaller numbers of drives, and for most home systems, the most common way the disks are attached is to the SATA controllers built into the motherboard. Non-Volatile Memory Express (NVMe) is a newer storage interface that is becoming very popular for flash storage devices. Just download the executable file on both devices and run it to open the tool. At a glance, changing idle3 and EPC settings seems to have done the job nicely; here is the same graph of head park rates per disk as before, but on a smaller timescale that makes individual head parks visible. Seagate provide a “Seachest” collection of tools for manipulating their drives, but rather more usefully to users of non-Windows operating systems like Linux they also offer an open-source openSeaChest.
When it comes to long-term data storage, there are several strategies and media types that Redditors recommend. It refreshes the disks SMART information every 5 min. ZFS and Btrfs both aim to modernize storage by combining filesystems and volume management, but… Monitoring and maintaining your storage media is one of the most important parts of keeping your data safe.
For ZFS users, automating fault responses with tools like ZED (ZFS Event Daemon) can simplify disk replacement and minimize downtime. Configuring your system to notify you when a disk has errors, or when the filesystem reports a degraded device, will ensure your system gets prompt attention when something goes wrong. Experienced enterprise storage managers also keep extensive notes including the model number, SKU and/or URL for reordering, purchase order information, warranty end date, warranty URL, and any other useful information about each drive. While the operating system typically provides device aliases based on the disk’s serial number, WWN, or some other static identifier, this does not provide all of the information you might want.
We can also see that the disk in Slot07 was recently swapped, and that Slot08 does not contain a disk and its locate LED is activated. SES provides a mechanism to query information from the enclosure, including temperature, fan speed, and status of power supplies. Many backplanes include support for SCSI Enclosure Services (SES).
