This is just FYI, that with some options fsck doesn't perform any check.
It was added to make some distros happy at boot time.
As to page allocation failure: it is an old issue, not always reproducible.
I'll add a respective ticket.
Thanks,
Edward.

I recieved this error few days ago.
What is md125?

Remounting this partition doesn't reproduce the error as it's
automatically fscked.
Are you sure that it is fscked at all?
Checking by fsck is rather long process...
And you were right, I used fsck.reiser4 -a that returns nothing if
reiser4.progs is 1.0.9.
I upgraded it to 1.1.0 and now fscking the partition.
But that script executed for 3 more nights and didn't make the error I
reported. PC wasn't rebooted in that time.
md125 is my daily snapshot partition. There's a script that fscks it,
then mounts and rsyncs /home to it daily at 2AM
cat /etc/cron.daily/rsnapshot.daily
#!/bin/sh
echo "### RSNAPSHOT DAILY ###"
fsck.reiser4 -a /dev/md125 && mount /mnt/backup && rsnapshot -c
/etc/rsnapshot.d/daily.conf daily || echo "Backup failure"
umount /mnt/backup
logger -s "### RSNAPSHOT DAILY OK###"
It is very crude, error prone and can be improved, I just had no time ;)
Thanks,
Edward.
Thanks
Dusan
