Hello,
After I have upgraded my htpc from openSuse 12.3 running kernel 3.7.10
to openSuse Tumbleweed running kernel 4.5.2; I am unable to mount my XFS
filesystem anymore.
I probably made some mistakes as I tried some things but did not note
them because I thought the problem would not be hard to solve.
As I still cannot mount it, I am asking for help.
Here is the details.
The XFS filesystem is on /dev/md0 device which is a RAID1 on top of two
partitions hosted on two hard disks.
cat /proc/mdstat gives
Personalities : [raid1]
md0 : active raid1 sdc1[1] sdb1[0]
2930264896 blocks super 1.0 [2/2] [UU]

dmesg outputs
[ 5525.861750] SGI XFS with ACLs, security attributes, realtime, no
debug enabled
[ 5525.862231] attempt to access beyond end of device
[ 5525.862232] md0: rw=32, want=5860529904, limit=5860529792
[ 5525.862234] XFS (md0): last sector read failed
Any pointers to fix this ? It seems the disks still contains a XFS
filesystem but for some reason, I cannot access it.
Thanks
