RHES3, ext3 and online resize : no hope ?

[Jean-Yves Picard]

Hello,

title say it all.

I have a RHES3, I want to grow a filesystem.
this file system is ext3

lvcreate --size 10m vg02
mke2fs -j /dev/vg02/lvol4

can it be grown while online ?
(e2fsprogs-1.32-15)

e2fsadm -L+10m -v /dev/vg02/lvol4
e2fsadm -- Sorry: 'ext2online' not found in any of /sbin /usr/sbin /usr/local/sbin /bin /usr/bin
e2fsadm -- ERROR: can't online resize

e2fsadm -- ERROR: /proc/mounts says /dev/vg02/lvol4 is mounted on /mnt/test-bo.
Please unmount it to resize.

where do I look for ext2online ? is it available for RHES_3_ ?

release notes for RHES_4_ hints that now FS can be grown online ...

can it be done in RHES_3_ ?

Not sure if possible, you may want to try upgrading your e2fsprogs package. Verify that the new package has the required command (ext2online).

Howdy,
If I remember correctly (It does happen sometimes :-) ) this functionality only appeared in the 2.6 series kernel and again IIRC RHES 3 is on a 2.4 kernel.
So no sorry you can't at the moment - you could always upgrade the box to RHES 4 provided you are on support??

regards
Ian

you can download (s)rpm's from the sourceforge site. should work without problems, i just recently did this on an old RH7.2 install!

logical volume is extended just fine, but filesystem won't grow !!

This could be a kernel limitation as described before. Try upgrading your kernel. I'm not sure if 2.6 is available for RHEL3. See RHN or download the 2.6 source for RHEL4.

Hello,

thanks all for help.
if it's a kernel limitation then that's settle it.

(Id' rather unmount Filesystem than upgrade the kernel)
