Hello,
I'm trying mount three disks from QNAP TS-469L in Linux (Fedora 25).
System correctly recognised disks and RAID5, but I have problem with
activate LVM with data.
In QNAP QTS system it was look this way:
Storage Pool 1 5,44 TB
├─DataVol1 (System) 5,38 TB (Free Size: ~300,00 GB)
└─DataVol2 509,46 GB (Free Size: ~400,00 GB)
In Fedora it looks that disks and RAID are recognised OK.
$ lsblk

inactive '/dev/vg1/lv1' [5,42 TiB] inherit
inactive '/dev/vg1/lv2' [512,00 GiB] inherit
If I understand correctly:
/dev/vg1/tp1 - it is QNAP "Storage Pool 1" (with real size 5,40 TiB)
/dev/vg1/lv1 - it is QNAP "DataVol1" (with virtual size 5,42 TiB)
/dev/vg1/lv2 - it is QNAP "DataVol2" (with virtual size 512 GiB)
So my data are on /dev/vg1/lv1 and /dev/vg1/lv2 but they are "inactive",
so they cannot be mounted.
$ sudo mount /dev/vg1/lv2 /mnt/lv2
mount: special device /dev/vg1/lv2 does not exist
I tried to activate it with lvchange but there is message that manual
repair of vg1/tp1 is required:
$ sudo lvchange -ay vg1/lv2
Check of pool vg1/tp1 failed (status:1). Manual repair required!
I tried command lvconvert --repair vg1/tp1 with no success:
$ sudo lvconvert --repair vg1/tp1
Using default stripesize 64,00 KiB.
Volume group "vg1" has insufficient free space (0 extents): 4096
required.
Please help howto repair/mount this LVM...
Best Regards,
Daniel
