Incompatibility between the reisrefs patches for 2.2.x and 2.4.x

Incompatibility between the reisrefs patches for 2.2.x and 2.4.x

[Vasil Kolev]

Maybe this is a know issue, but nonetheless.....
I have dual coppermine/930 machine with 1.2G ram, kernel 2.4.5. I used
reiserfs for my  /home and /var partitions. When tried downgrading to
2.2.19, I got errors  in syslog like 'can't find superblock' ... ( I don't
have them, /var wasn't mounted, and i had to return the machine in
production state... ). Does someone has any idea about this, how could I
downgrade to 2.2.19 ?

2.4 kernels can work with both 3.5 reiserfs disk format (old) and 3.6
(new). 2.2 kernels---only with 3.5. Probably, you have created your
file-systems in the new format.

You can boot 2.4 kernel, create new file-system large enough with
/sbin/mkreiserfs -v1 (old format), copy existing files there by tar or
cpio and then update /etc/fstab to mount file-system just created. Now,
you can work both with 2.2 and 2.4 kernels.

Keep in mind, that 3.5 format has some limitations concerning file size
etc. Check faq at namesys.com for details. On the other hand, 3.5 often
considered more stable.

Can I use the new format with 2.2? I don't have enough space to do that...
I would live with the limitations ... I just want it to work :)

I am afraid you cannot. Not now at least. Sorry.
