RE: resizing LUN (not file system) while the file system (ext3) isonline

["Andrey Dmitriev" <admitriev@mentora.com>]

So,

Should online resizing of the file system work out of the box?
Should online resizing of the LUN work out of the box?
When will the new e2fsprogs 'officially' officially be out?

I am a bit confused.

[root@bop-prod-db1 ~]# uname -a
Linux bop-prod-db1 2.6.9-22.0.1.ELsmp #1 SMP Tue Oct 18 18:39:02 EDT 2005
x86_64 x86_64 x86_64 GNU/Linux
[root@bop-prod-db1 ~]# rpm -qa|grep 2fs
e2fsprogs-1.35-12.3.EL4
e2fsprogs-devel-1.35-12.3.EL4
e2fsprogs-1.35-12.3.EL4

Thanks ,
-Andrey

Yes.  We patched our e2fsprogs to enable "-O resize_inode" in mke2fs by
default for RHEL-4 (the option has negligible effect other than to add a
tiny amount of space for ext3 group descriptors to grow into, enabling
online resize); upstream e2fsprogs has just enabled it by default too
for the forthcoming e2fsprogs-1.39 release.

Cheers,
