filesystem online/mounted resize support

Adam Garsha — Wed, 03 May 2006 11:26:16 GMT

Which of these filesystems support online resize (i.e. mounted) when the logical volume underneath has been extended?

ext2?
ext3?
reiserfs?

Thanks!

Shalom,

Since November of 2004, ext3 has supported online resize.

You need to check with your linux distribution, which you have not revealed to us.

Hi Adam,

ext2, ext3 can also resize
http://sourceforge.net/projects/ext2resize/
http://ext2resize.sourceforge.net/

reiserfs can resize using following command.
#resize_reiserfs /path/to/dev
#mount -o remount,resize /path/to/dev
in order to reduce the reiserfs size you must umount the partition.

both tools you need to umount the file system to reduce the size.

Sung

Thanks, Suse 9.3.

I'll go with reiserfs since Suse leans that way by default. This is just a workstation.

Man, I miss advFS...
