LV raid can't be mounted on startup

everwisher · 2019-10-29 10:03:17

I have 6 hard drives and divided them all to 2 partitions, a larger one and a smaller one. Then I created a linear JBOD LV from all the larger partitions and a raid-5 LV from all the smaller ones. The lvm scheme has been running without any issue during my Ubuntu, Mint, Fedora and Manjaro times.

Recently I decided to switch to Arch Linux but found myself unable to successfully boot up the system for the failure to mount the raid-5 LV. Once that volume is commented in fstab, everything works fine and I can use

# sudo vgchange -ay

to activate the vg and mount the raid5 lv on it manually.

However my samba shares resides on that lv and it now can't be used on a headless startup.

I even rebuilt the lv but the issus persists.

Anyone can tell me what's the underlying blunder please?

Is your / filesystem on the raid or on the jbod ?
for raid, see https://wiki.archlinux.org/index.php/LV … o_for_RAID
If jbod, https://wiki.archlinux.org/index.php/LV … mkinitcpio

If you have things configured correctly , do those other distros use the same lvm2 version as archlinux ?
Do they use the same lvmetad setting ?

Well, all the linux distros i’ve used along side the hard drive lvs reside in an SSD, which is divided into two partitions: an esp and a system partition for /

I'm not aware of the use of lvmetad but I didn’t change the lvs back when using ubuntu, mint and fedora. I don’t know if any of those previous distros made any changes to them.

So your / is not on the JBOD or lvm raid ?
It's very unclear to me how your partitions are setup.

Once everything is mounted / activated run (as root)

# lsblk -f
# fdisk -l

and post their outputs, also include /etc/fstab .
Full journal / dmesg from a boot without and with the lvm raid commented in fstab would also help.

Arch Linux
