RE: reiser4 - transparent compression

Thank you again for your support.

I am using separate disk with LVM and in it I have Reiser4, is there any possibility to extend reiser4 fs ? I do not find tools for that. Will it extend once LVM partision will extend?
Or it should be done offline?

Didn't find such tools in /opt/reiser4progs/sbin/*, or at least similar name, I have only "debugfs.reiser4 ; fsck.reiser4 ; make_reiser4 ; measurefs.reiser4 ; mkfs.reiser4"

I would suggest to use a dedicated partition with zstd1 compression in intelligent mode.
Simply specify "-o compress=zstd1" when formatting a partition.

Thanks,
Edward.
