Subject: [linux-lvm] xfs_growfs after lvextend don't increase mounted size.
Date: Wed, 01 Nov 2006 23:42:11 +0100 [thread overview]
Message-ID: <454922C3.8060902@mmtab.se> (raw)
Hi!
I've got a 6.5TB xfs filesystem on a LVM2 volume. I wanted to increase
the size of the fs so I added another ~10TB to the volume. Every step
taken was successfull, (ie no errors) but the filesystem size remained
unchanged even after the xfs_growfs.
What I did was the following:
I extended the lvm using pvcreate, vgextend and finally lvextend. pvscan
gives:
PV /dev/sda1 VG vg01 lvm2 [1.59 TB / 0 free]
PV /dev/sdb1 VG vg01 lvm2 [1.59 TB / 0 free]
PV /dev/sdc1 VG vg01 lvm2 [1.59 TB / 0 free]
PV /dev/sdd1 VG vg01 lvm2 [1.59 TB / 0 free]
PV /dev/sde1 VG vg01 lvm2 [2.00 TB / 0 free]
PV /dev/sdf1 VG vg01 lvm2 [2.00 TB / 0 free]
PV /dev/sdg1 VG vg01 lvm2 [2.00 TB / 0 free]
PV /dev/sdh1 VG vg01 lvm2 [2.00 TB / 0 free]
PV /dev/sdi1 VG vg01 lvm2 [1.55 TB / 0 free]
Total: 9 [15.91 TB] / in use: 9 [15.91 TB] / in no VG: 0 [0 ]
and lvdisplay:
--- Logical volume ---
LV Name /dev/vg01/lv01
VG Name vg01
LV UUID rDSEQ3-DdhV-oLci-nNYT-dMdX-cppA-7v1r3e
LV Write Access read/write
LV Status available
# open 1
LV Size 15.91 TB
Current LE 4169996
Segments 9
Allocation inherit
Read ahead sectors 0
Block device 253:0
After xfs_growfs /vol1 ( mounted fs ) df -h gives:
/dev/mapper/vg01-lv01
6.4T 6.4T 36G 100% /vol1
The fs remains in previous size!!
# cat /sys/block/dm-0/size
34160607232
which is equal to 15.91 TB
Have I missed something when I extended the volume / growed the xfs fs?
The system running xfs is a Fedora Core 4, 2.6.15-1.1831_FC4smp,
lvm2-2.01.08-2.1, xfsprogs-2.6.13-4
