reiserfs - drives me crazy

Hi,

Everytime I boot, reiserfs tells me, that my filesystem is corrupted. Every time. The repair checks me to reboot (which runs fine), I shut down the computer okay - next boot reiserfschck tells me "Wrong number of used blocks".

Okay, what do I know? reiserfs says:

Switch to Ext3 or some other more reliable filesystem (XFS,JFS ?)

You could (and should) use the install-cd or another live-cd like knoppix and run the file-system check from there:
reiserfsck /dev/_your_device_
possibly with the argument --fix-fixable
make sure it is not mounted...
Be very careful (stay away!) from using --rebuild-tree - this could wreck everything.
...from the manual-page of reiserfsck:

in /tmp there is a file called .keep - I think you want to recreate that after you recreate /tmp - I was reading about strange problems during upgrades when this was not present anymore (probably keeps emerge from deleting stuff in there which is still in use)
You don't need to copy /dev - but make sure you create /dev/null and /dev/console before you boot - else you will have the problem to have to do it on the error you will get because these critical files are missing
(just copy these two...)

/proc and /sys just needs to be created - do not copy them

and: use "cp -a" to keep all the permissions intact

could you post:
the command you gave - which gave these errors
also:
the output of "mount" - and/or make sure the partition you are copying to is mounted rw
and: you must run the copy-command as root - else you will not have permission to read some files or to create them with the right permissions
------------------------------------------------------
a suggestion of how to do it...

the new partition is mounted at /new-part (rw)

as root:

cd / && cp -a `/bin/ls -1Ab | egrep -v "^new-disk$|^boot$|^proc$|^dev$|^sys$|^tmp$"` /new-part

or

cd / && cp -a /bin /etc /home /lib /media /mnt /opt /root /sbin /usr /var /new-part

are two variants to do it - make sure _nothing_ is mounted on /mnt or /media or anywhere else (would be recursively copied also...)

after the command finishes - create:
/boot /dev /proc /sys /tmp

and copy /dev/console and /dev/null to /dev on the new partition
and create /tmp/.keep there

then change fstab (on the new partition) to reflect the change (different device for / and different filesystem - including mount-options...)
and also your grub.conf for the same reason
reboot
