HDD never spin down

jwb · Oct 5, 2022

It is still confusing for me how to make it work.

Using

Code:

blktrace -d /dev/sdc -o - | blkparse -i -

I see this which causes the disks to spin up:

Code:

  8,32   7      173  1155.524252951  4140  I   W 14991898680 + 8 [z_wr_int_1]
  8,32   7      174  1155.524254007  4140  D   W 14991898680 + 8 [z_wr_int_1]
  8,32   7      175  1155.525452948 558788  A   W 14856242120 + 32 <- (8,33) 14856240072

Code:

  8,32   4      616  1155.464635571 558694  P   N [z_wr_iss]
  8,32   4      617  1155.464635796 558694  U   N [z_wr_iss] 1
  8,32   4      618  1155.464636009 558694  I   W 14855845584 + 8 [z_wr_iss]

Something from zfs keeps the disks spinning?

Hello, I found a way to keep unused disk standby.
I see all hdd become active when I use lvm commands (like lvdisplay), and pvestatd will call lvm functions to get the status of default local-lvm storage.
so I edit the /etc/lvm/lvm.conf, append a new filter rule in

devices{
global_filter []

}

now it is

global_filter = [ "r|/dev/zd.*|", "r|/dev/mapper/pve-.*|", "r|/dev/sdb.*|" ]

and now pvestatd will not awake my /dev/sdb

I also tried this, however this can have an adverse side-effect: In my case, there is an LVM PV on that drive. When I disable it via a global filter, the VG does not get started at all.

I have resorted to exclude the device only for pvestatd, which indirectly uses /usr/share/perl5/PVE/Storage/LVMPlugin.pm in lvm_vgs():

Perl:

    #my $cmd = ['/sbin/vgs', '--separator', ':', '--noheadings', '--units', 'b',
    my $cmd = ['/sbin/vgs', '--config', 'devices { global_filter=["r|/dev/zd.*|","r|/dev/mapper/.*|","r|/dev/sda.*|"] }', '--separator', ':', '--noheadings', '--units', 'b',
               '--unbuffered', '--nosuffix', '--options'];

However, it ssems there are two more calls to LVM, like:

Code:

    $cmd = ['/sbin/pvs', '--config', 'devices { global_filter=["r|/dev/zd.*|","r|/dev/mapper/.*|","r|/dev/sda.*|"] }', '--separator', ':', '--noheadings', '--units', 'k',
            '--unbuffered', '--nosuffix', '--options',
            'pv_name,pv_size,vg_name,pv_uuid', $device];

and

Code:

    my $cmd = [
        '/sbin/lvs', '--separator', ':', '--noheadings', '--units', 'b',
        '--unbuffered', '--nosuffix',
        '--config', 'report/time_format="%s" devices { global_filter=["r|/dev/zd.*|","r|/dev/mapper/.*|","r|/dev/sda.*|"] }',
        '--options', $option_list,
    ];

I have successfully disabled pvestatd via modification of /usr/share/perl5/PVE/Storage/LVMPlugin.pm.

However, I reverted that change, because it had an adverse side-effect: Every night, upon automatic backup, the first backup always failed with a timeout, because the disk did not spin up fast enough, giving an error like:

Code:

cannot determine size of volume 'local-lvm:vm-120-disk-0' - command '/sbin/lvs --separator : --noheadings --units b --unbuffered --nosuffix --options lv_size /dev/pve/vm-120-disk-0' failed: got timeout

Something from zfs keeps the disks spinning?

Same issue here. Did you find a solution?

Dunuin · Dec 24, 2023

Probably pvestatd polling storages? Wasn't that done every 8 seconds?

jofland · Dec 25, 2023

Maybe it is pvestatd, but not every 8 seconds. The disk starts spinning each time after several ten minutes.

What I have done so far:

create a zfs patition "local-backup2" on /dev/sda at node "pve01"
mounted the zfs partition as directory "local-backup"
added a storage "backup-dir" in /local-backup2" at datacenter for content "VZDump backup file"
excluded the devices in lvm.conf from scanning
activated spindown in hdparm.conf
excluded /dev/sda from smartd scans

Spindown works as configured in hdparm.conf. But the disk starts spinning with same blktrace messages as user flove (see above).

Code:

root@pve01:~# mount |grep backup
local-backup2 on /local-backup2 type zfs (rw,relatime,xattr,noacl,casesensitive)
local-backup2/subvol-113-disk-1 on /local-backup2/subvol-113-disk-1 type zfs (rw,relatime,xattr,posixacl,casesensitive)
local-backup2/backup-dir on /local-backup2/backup-dir type zfs (rw,relatime,xattr,noacl,casesensitive)

Code:

root@pve01:~# tail -4 /etc/lvm/lvm.conf
devices {
     # added by pve-manager to avoid scanning ZFS zvols
     global_filter=["r|/dev/disk/by-label/local-backup2.*|", "r|/dev/sda.*|", "r|/dev/zd.*|", "r|/dev/mapper/pve-.*|"]
}

Code:

root@pve01:~# tail -4 /etc/hdparm.conf
/dev/disk/by-id/ata-ST1750LM000_HN-M171RAD_S34Dxxxxxxxxxx {
        spindown_time = 120
}

Code:

root@pve01:~# cat /etc/smartd.conf
[...]
/dev/sda -d ignore
DEVICESCAN -d removable -n standby -m root -M exec /usr/share/smartmontools/smartd-runner
[...]

Dunuin · Dec 25, 2023

As long as that directory storage isn't disabled pvestatd will poll it all the time keeping the disk awake.

Hi,

here is a checklist what can keep the disk running

Excuse me, respected Professor Wolfgang. May I ask for your advice on the hardware export issue of Proxmox.

Spindown works as configured in hdparm.conf. But the disk starts spinning with same blktrace messages as user flove (see above).

Finally I found the reason: I accidentaly installed one LXC on this hdd. After moving the LXC to the ssd it works; the hdd keeps standby status.

sanchO · Jan 16, 2024

Some time has passed since the post have been created, anyone aware if this perhaps has been implemented?

jofland · Jan 16, 2024

What do you mean with "implemented"?

Just follow the steps in post #27. Works for me now.

Hi, looks like an option for my problem. But i cant get the code work. I copied the following section to the config file. But i am getting the following error:
"Parse error at byte 111831 (line 2454): unexpected token". Any suggestions? Sorry, i am not an expert in such deep linux stuff and new in proxmox universe

I can't get this to work. I am using hd-idle

Things I have tried

disabling smartd
disabling smartmontools
disabling pvestatd

LVM devices

Code:

 global_filter=["r|/NAS.*|", "r|/dev/disk/by-label/NAS.*|", "r|/dev/sda.*|", "r|/dev/sdb.*|", "r|/dev/sdc.*|", "r|/dev/sdd.*|", "r|/dev/zd.*|", "r|/dev/mapper/pve-.*|"]

Changing from storage directories > ZFS storage

And I still can't power down for more than a few seconds

Any suggestions?
