Hello,
I'm trying online resizing with RBD + XFS. But when i try to make a xfs_growfs, it doesn't seen the new size. I don't use partition table, os is debian squeeze / kernel 3.8.4 / ceph 0.56.4.
It seems that the mounted file system prevents update the block device size ?
If the file system is not mounted, or if I unmount + mount, xfs_growfs works as expected.
#### ORIGINAL SIZE ####
# parted /dev/rbd1 print
Model: Unknown (unknown)
Disk /dev/rbd1: 105MB
Sector size (logical/physical): 512B/512B
Partition Table: loop
Number Start End Size File system Flags
1 0,00B 105MB 105MB xfs
#### RBD RESIZE ####
# rbd resize rbdxfs --size=200
Resizing image: 100% complete...done.
#### SIZE NOT CHANGE IF FS ON RBD1 IS MOUNTED ####
# parted /dev/rbd1 print
Model: Unknown (unknown)
Disk /dev/rbd1: 105MB
Sector size (logical/physical): 512B/512B
Partition Table: loop
Number Start End Size File system Flags
1 0,00B 105MB 105MB xfs
#### UMOUNT FS --> SIZE OK ####
# umount /mnt/rbdxfs
# parted /dev/rbd1 print
Model: Unknown (unknown)
Disk /dev/rbd1: 210MB
Sector size (logical/physical): 512B/512B
Partition Table: loop
Number Start End Size File system Flags
1 0,00B 210MB 210MB xfs
Any Ideas ?
Thanks
