This will activate the fault LED for element 9 (Slot 08) on the first SES device. You can avoid any uncertainty by enabling the “locate” or “fault” LED for the drive you mean to replace. This example creates a new GPT partition scheme on da36, creates a 4 GiB swap partition aligned to 1 MiB boundaries, and then adds a ZFS partition with the label e3s01-ZGY0XH87 using the remainder of the space on the disk.

How do I connect to an unattended desktop with AnyDesk?

For chassis with larger numbers of drives, or when connecting external JBOD chassis, it is common for the drives to connect to a specialized board that provides power and routing for the SATA/SAS signals to the controller. When building a storage system, there are many different ways the disks might be connected to the system. NVME-oF allows storage devices and arrays in remote chassis to be connected to local motherboards. NVMe storage comes in many form factors, from small M.2 devices to U.2 and other hot-swappable formats intended for servers. NVMe connects storage devices directly to the PCIe bus, offering extremely low latency and high throughput.
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.

  • Ensure device health & easy replacements with these valuable tips.
  • My question is – is there a way to tell if a certain disk suffers from the issue prior to purchasing?
  • Hello,Like many users of Seagate Exos drives, I have found that they park their heads very aggressively, approximately every 2 minutes.
  • Secondly what are your disk monitoring refresh intervals and what do you use on your system to monitor SMART disk health?
  • If your system has multipath SAS, each disk will be present more than once, and you should use the gmultipathcommand to deduplicate your disks and for labeling as well.
  • To prevent parking the heads at all a value greater than 128 may do the job (254 is a common choice, as the highest-power setting available), but it’s possible that some disks won’t behave this way because the ATA specification refers only to spinning down the disk and does not specify anything about parking heads.

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.

Other interfaces for remote storage include iSCSI, Fiber-Channel, Infiniband, RoCE, and others, 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
SAS disk reservations provide the ability to connect to the disk redundantly—or even across multiple machines—while ensuring it is only used by one of them at a time. SAS provides many more features than SATA does—including full duplex operations, advanced error recovery, multipath, and disk reservations. It too was an extension on an existing interface bus which offered greatly improved performance. 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. These concepts also apply to other operating systems, but the tools might differ slightly.

Storage Media Options

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. With modern, especially Enterprise grade hard drives being able to have hundreds of thousands of head park operations in their service life, is this really an isssue? With the tools presented here, the reader is well armed to react to failed disks and ensure that the wrong disk isn’t accidentally pulled. However, if reveryplay a disk has died entirely, or a slot is empty, it might not have a device name. Sesutil can also be used to locate the disk in the physical array.While the SES data tells us that there is an 8 TB disk in Slot 06, it does not tell us which slot in the chassis corresponds to 06. Looking at a few items from the output, we can see the device names (/dev/da0 and /dev/da7 respectively) of the disks in Slot00 and Slot07.
I noticed that even when doing nothing, I hear the sound of drives working every few seconds. I gave up and just built a Windows Storage Space with tiering and the drives are now effectively silent. I guess it depends on the drives, but don’t think you’ll find any software solution. My Seagate Exos enterprise drives make almost 0 noise actually. The system is never idle really, it’s a server. What causes the constant load on the disk?
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.

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.

Understanding Storage Protocols

If you need more advanced functionality than mpsutil provides, LSI provides their native tools sas2ircu and sas3ircu for FreeBSD. On my system, this command produces a bright red LED lit for that slot, physically highlighting the correct drive to replace. So, to activate the LED for the first disk displayed above, we first need to determine the enclosure handle number (0001), and then the slot number of the disk (03). This partitions each disk and labels the ZFS partition with the enclosure, slot, and serial number of the corresponding disk. As with a number of tools in FreeBSD, sesutil supports outputting JSON via the libxo library.
I set power mode to Idle and advanced power management to the lowest setting (1) which should spin down the disk after 5 mins. Hello,Like many users of Seagate Exos drives, I have found that they park their heads very aggressively, approximately every 2 minutes. AnyDesk allows you to establish remote desktop connections between devices and opens up unprecedented possibilities of collaborating online and administrating your IT network. Its primary purpose is to grant bidirectional remote access between personal computers and mobile devices. To do this, both devices must have the program installed and must allow access through the use of security keys. The current settings for a disk can be queried with the –showEPCSettings flag.
In this case, there are at least two disks that I probably need to configure, since /dev/sde seems to be parking as often as about every 4 minutes (0.004 Hz) and /dev/sdc is only parking slightly less often. The smartmon_load_cycle_count_value metric seems like it would be the right one to query, but that actually expresses a percentage value (0-100) representing how many load cycles remain in the specified lifetime- on reaching 0 the disk has done a very large number of load cycles. It does support reading arbitrary metrics from text files written by other programs with its textfile collector however, which is fairly easy to integrate with arbitrary other tools.

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.
