ok, so I did a remount with noattrs instead of noattr (picked that up on
the kernel mailing list... is there any documentation for this mount
options? man mount definitely doesn't talk about this!)
all the system partitions are now mounted noattrs:
mstoll@martin1:/usr$ mount | grep reiserfs
/dev/hda5 on / type reiserfs (rw,noattrs)
/dev/hda6 on /tmp type reiserfs (rw,noattrs)
/dev/hda7 on /var type reiserfs (rw,noattrs)
/dev/hda8 on /usr type reiserfs (rw,noattrs)
/dev/hda10 on /home type reiserfs (rw,noattrs)
/dev/sda1 on /var/external type reiserfs (rw)
Now things seem to be more or less back to normal. Still having
problems with symlinks, though... I can't delete them?
mstoll@martin1:/usr/share/doc$ ls -ld gfortran-4.0* gcc-4.0-base/
drwxr-xr-x 5 root root 432 2006-02-13 11:04 gcc-4.0-base/
lrwxrwxrwx 1 root root 12 2006-02-01 15:21 gfortran-4.0 -> gcc-4.0-base

mstoll@martin1:/usr/share/doc$ sudo mv gfortran-4.0 /tmp
mv: cannot remove `gfortran-4.0': Operation not permitted
mstoll@martin1:/usr/share/doc$ sudo rm gfortran-4.0
rm: cannot remove `gfortran-4.0': Operation not permitted
But now lsattr returns "Inappropriate ioctl for device".... oh well:
mstoll@martin1:/usr/share/doc$ lsattr -d gfortran-4.0 gcc-4.0-base/
lsattr: Inappropriate ioctl for device While reading flags on
gfortran-4.0
lsattr: Inappropriate ioctl for device While reading flags on
gcc-4.0-base/
I guess that remounting the filesystem doesn't clear the special
treament that symlinks get? I guess a bug in the kernel/mount ?
Anyways, I'll try rebooting, having changed the fstab settings to
noattrs, to see if it works better then.
BTW: I also tried just clearing all the attributes before. That seemed to work
for many things, but not for special devices in /dev ... It looks like
even though special devices aren't supposed to have inode attributes (at
least they can't be read or set), if they exist because they were random
from old reiserfs version, then they are still used! This is probably a
separate bug, but should be addressed/forwarded to reiserfs developers
