The server enters emergency mode after a reboot. There are two disks on the machine, a ssd /dev/sda1 and a hdd /dev/sdb1. Originally the ssd was mounted to / and the hdd was mounted to /home.
Now the home directory is missing, and lsblk shows the two disks are still there. So I first tried to mount the hdd back manually. But it fails, saying cannot mount a disk with type "LVM2_member".
It seems the disk was managed using lvm, so I used pvs, vgdisplay, lvdisplay to inspect, but none of those command shows anything.
So it seems the lvm managed volume metadata are all missing. I think I should manually reconstruct those structures.
pvcreate /dev/sdb1
It failed, reporting "Can't initialize physical volume /dev/sdb1 of volume group cs without -ff."
I think it means the disk belongs to the volume group cs. But vgdisplay shows nothing, and I cannot create logical volume of vg cs, because it does not exist.
Here are my questions:
- Why the pvs are all gone? Where should I begin to do troubleshooting?
- What should I do if I want the /home directory back, should I start from creating pv again? Will -ff remove the data on the disk?
Update:
smartctl -x /dev/sdb shows the drive's User Capacity, Logical block size, Logical Unit id, Decice Type and Local Time, they are all normal results, but it says SMART support is unavailable.
Result:
Vendor AVAGO
Product: MR9361-8i
Revision: 4.68
Compliance: SPC-3
User Capacity: 4.00 TB
Logical block size: 512 bytes
Logical unit id: 0x600605b011806720ff00001901d6ca4a
Device type: disk
Local Time is: Wed Jun 12 1:40:01 2024 EDT
SMAERT support is: Unavailable - device lack SMART capability
Read cache is: Enabled
Writeback Cache is: Disabled
And I tried pvcreate with --uuid and the --restorefile, the file is
/etc/lvm/backup/cs, but it still shows "Can't initialize physical volume /dev/sdb1 of volume group cs without -ff", and vgchange does not work beacuse there is no vg cs.
What confuses me is, the pvreate command refuse to restore the pv metadata, saying sdb1 is already part of the volume group cs. Meanwhile, vgdisplay and all other commands say this volume group does not exist.
About the raid controller:
I forgot to mention the hardware raid controller. It has 8 maximum slots, and now only two of them (slot 0 and slot 2) are used, each drive is configured as raid0 mode, so it is juat like JBOD mode in may aspects. But I am not sure whether this could have caused other delicate issues that resulted all this. The details are as below:
