[SOLVED] LVM-Thin pool is inactive after system reboot

[Froto]

Hi,

So I'm trying to create a new LVM-thin pool to use with a new SSD I've installed.

I've created the pool with:

lvcreate -L 440G -n vmstuff SEi
lvconvert --type thin-pool SEi/vmstuff

after a restart, Proxmox cannot start my containers because it cannot find the VM disks.

lvscan
  inactive          '/dev/SEi/vmstuff' [440.00 GiB] inherit
  ACTIVE            '/dev/pve/swap' [8.00 GiB] inherit
  ACTIVE            '/dev/pve/root' [29.50 GiB] inherit
  ACTIVE            '/dev/pve/data' [64.74 GiB] inherit

What is causing this to happen? I don't have this issue if I create a normal LVM.

 LV      VG  Attr       LSize   Pool Origin Data%  Meta%  Move Log Cpy%Sync Convert
  vmstuff SEi twi---tz-- 440.00g
  data    pve twi-a-tz--  64.74g             0.00   0.03
  root    pve -wi-ao----  29.50g
  swap    pve -wi-ao----   8.00g

 VG  #PV #LV #SN Attr   VSize   VFree

  pve   1   3   0 wz--n- 118.99g 14.75g

PV         VG  Fmt  Attr PSize   PFree
  /dev/sda3  pve lvm2 a--  118.99g 14.75g
  /dev/sdb1  SEi lvm2 a--  465.75g 25.50g

Any help would be greatly appreciated

Thanks,
Michael L.

You could check your kernel boot line? (in grub)
Also, you could check thin-provisioning-tools is installed?
I always create the thin pool with the -T switch to lvcreate, what is the advantage of the two stage create?

thanks for reminding me

nano /etc/default/grub
GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="Proxmox Virtual Environment"
GRUB_CMDLINE_LINUX_DEFAULT=""
GRUB_CMDLINE_LINUX=" rootdelay=8 "

Adding root delay 8 seems to fix the issue.

Thank you
