Online resize2fs: Operation not permitted While trying to add group #14080
I am running Oracle Enterprise Linux x64 5.5 on an HP Proliant DL380 G6 attached to various SAN's via fibre channel. I have setup multipath, edited multipath.conf, lvm.conf, and after some trial and error, everything behaves and looks as it should in regard to multipath.
However, when I try to resize a multipath ext3 lvm filesystem, The operation runs for a while, but then dies and I get the above error. I then see this error in /var/log/messages:
EXT3-fs warning (device dm-9): ext3_group_add: No reserved GDT blocks, can't resize
-I am only using the /dev/mapper/ paths to the filesystem (ie, resize2fs /dev/mapper/testvol-lvol1 128G)
-if I unmount the filesystem, resize2fs works fine
-Have tried removing and re-adding journal file via tune2fs with no luck
-The VG has plenty of room in it and is composed of a 100GB and 200GB partition.
-Inode resize is on in the filesystem
I am wondering if online resize2fs is only for small filesystems or not recommended as a best practice or just not generally done??? As I mentioned, the operation works fine offline if I unmount the filesystem, but this won't be an option once system is in production.
Any ideas? Thanks in advance!
Thanks for the reply!
I meant to say that inode resize was on in original post, not resize inode.

I just created FS today as I am testing, so it is an EXT3 filesystem. I just recreated a new FS from scratch from command line and same results. Started with a 400mb filesystem size and it died at 45GB with same error. I am wondering if online resize2fs only works with smaller filesystems less than 50GB...?
Any ideas on this?
