[linux-lvm] Removing disk from raid LVM

Libor> here it comes.
Great, this is a big help, and it shows me that you are NOT using
RAID5 for your backup volumes. The first clue is that you have 4 x
3tb disks and you only have a VG with 10.91t (terabytes) of useable
space, with a name of 'vgPecDisk2'.
And then none of the LVs in this VG are of type RAID5, so I don't
think you actually created them properly. So when you lost one of the
disks in your VG, you immediately lost any LVs which had extents on
that missing disk. Even though you did a vgcfgrestore, that did NOT
restore the data.
You really need to redo this entirely. What you WANT to do is this:
0. copy all the remaining good backups elsewhere. You want to empty
all of the disks in the existing vgPecDisk2 VG.
1. setup an MD RAID5 using the four big disks.
mdadm --create -l 5 -n 4 --name vgPecDisk2 /dev/sda /dev/sdb /dev/sdd /dev/sdg
2. Create the PV on there
pvcreate /dev/md/vgPecDisk2
3. Create a new VG ontop of the RAID5 array.
vgcreate vgPecDisk2 /dev/md/vgPecDisk2
3. NOW you create your LVs on top of this
lvcreate ....
The problem you have is that none of your LVs was ever created with
RAID5. If you want to do a test, try this:
lvcreate -n test-raid5 --type raid5 --size 5g --stripes 4 vgPecDisk2
and if it works (which it probably will on your system, assuming your
LVM tools have support for RAID5 in the first please, you can then
look at the output of the 'lvdisplay test-raid5' command to see how
many devices and stripes (segments) that LV has.
None of the ones you show have this. For example, your lvBackupVokapo
only shows 1 segment. Without multiple segments, and RAID, you can't
survive any sort of failure in your setup.
This is why I personally only ever put LVs ontop of RAID devices if I
have important data.
Does this help you understand what went wrong here?

Libor> I think i have all PV not on top of raw partitions. System is on mdraid and backup PVs are
Libor> directly on disks, without partitions.
Libor> I think that LVs:
Libor> lvAmandaDaily01old
Libor> lvBackupPc
Libor> lvBackupRsync
Libor> are old damaged LVs, i left for experimenting on.
Libor> These LVs are some broken parts of old raid?
Libor> lvAmandaDailyAuS01_rimage_2_extracted
Libor> lvAmandaDailyAuS01_rmeta_2_extracted
Libor> LV lvAmandaDailyBlS01 is also from before crash, but i didn't try to repair it (i think)
