[gentoo-user] [OT] Resize of a reiser4 filesystem?

[gentoo-user] [OT] Resize of a reiser4 filesystem?

[Alexander Skwar]

Hello!

I'd looking for a way to resize my reiser4 filesystems.
Best would be an "online" option (ie. one, that does
not require an unmount of the fs).

In older packages, I found a man page for a resize_reiser4
tool (not sure about the name). Even this manpage is gone
in sys-fs/reiser4progs-1.0.4, which I've got currently
installed.

If there's no "online" way, an offline way would be
appreciated as well.

Thanks a lot,

Alexander Skwar

AFAIK, and according to the README in the reiser4progs, Reiser & Co have 
not gotten around to implementing the resizer for reiser4.

So, for an 'offline' option, backup, resize, reformat, restore....

Since practically all my partitions are LVM, not being able to resize
really takes reiserfs4 out of the running for me. Of course, by the
time a resizer is available, a significant number of bugs should have
also been worked out, and perhaps it will even be included in the
mainline kernel.

Yes, I'm looking forward to the repacker.

I've tried to follow a couple of recent lkml threads on reiser4, and 
well, there still seems to be a lot of resistance to including it in 
mainline.  I don't think we'll see it soon...

For resizing, your best bets (for journalling fs) are ext3 and reiser3.  
XFS is growable, but not shrinkable.
