I extended an LV to 12.28TB and ran xfs_growfs on the mount point, lv0.
This appeared to work fine except that after this, the filesystem didn't
appear any larger.
rajones@mapdata<~>$ df -h /lv0
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg0-lv0 4.1T 2.9T 1.3T 70% /lv0
This was the size of the filesystem before the xfs_growfs was run and after.
Is it possible the LV or VG could be corrupted in some way? Or is the
problem likely with the xfs filesystem? I've run xfs_repair on
/dev/mapper/vg0-lv0 and it complete successfully. I can mount the
filesystem with no errors and see the existing data but the size still
shows up wrong.
The System in question:
The PVs in the VG are LUNs on an external FC attached RAID unit.
The system OS is FC3 running kernel 2.6.12-1.1381_FC3smp,
xfsprogs-2.6.13-2, lvm2-2.00.25-1.01.
What happened:
root@mapdata<~>$ lvextend -l +33528 /dev/vg0/lv0 /dev/sdi1 /dev/sdj1
/dev/sdk1 /dev/sdl1 /dev/sdm1 /dev/sdn1
After the extend I have the following LV.
root@mapdata<~>$ lvdisplay
--- Logical volume ---
LV Name /dev/vg0/lv0
VG Name vg0
LV UUID qbk6r9-RxpP-Bx9Y-joJV-4ptl-PSNE-PuXX1X
LV Write Access read/write
LV Status available
# open 2
LV Size 12.28 TB
Current LE 50292
Segments 11
Allocation inherit
Read ahead sectors 0
Block device 253:0
root@mapdata<~>$ xfs_growfs /lv0
Results in no change in the mounted filesystem size.
root@mapdata<~>$ xfs_repair -o assume_xfs /dev/mapper/vg0-lv0
Phase 1 - find and verify superblock...
bad primary superblock - inconsistent filesystem geometry information !!!
attempting to find secondary superblock...
[cut rest of xfs_repair output]
The xfs_repair finds secondary superblock and completes successfully but
when I mount I get the same result as before:
rajones@mapdata<~>$ df -h /lv0
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg0-lv0 4.1T 2.9T 1.3T 70% /lv0
Any suggestions?
Thank you,
Randall
