I can barely keep my PC running for half an hour before it crashes. There seem to be serious problems with the hard disk as /var/log/messages documents shortly before the crash: Mar 15 07:42:00 linux kernel: ReiserFS: dm-0: warning: vs-13070: reiserfs_read_locked_inode: i/o failure occurre d trying to find stat data of [95 17188 0x0 SD] Mar 15 07:42:02 linux kernel: ReiserFS: warning: is_tree_node: node level 49776 does not match to the expected o ne 1 Mar 15 07:42:02 linux kernel: ReiserFS: dm-0: warning: vs-5150: search_by_key: invalid format found in block 823 8. Fsck? I get tons of the above errors. ReiserFS runs /home ona LVM with 2 disks: #mount /dev/hdd2 on / type reiserfs (rw,acl,user_xattr) proc on /proc type proc (rw) tmpfs on /dev/shm type tmpfs (rw) devpts on /dev/pts type devpts (rw,mode=0620,gid=5) /dev/mapper/system-home on /home type reiserfs (rw,acl,user_xattr) /dev/fd0 on /media/floppy type subfs (rw,nosuid,nodev,sync,fs=floppyfss,procuid) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) usbfs on /proc/bus/usb type usbfs (rw) Can someone help? ReiserFS seems to suggest fsck. I have never used that though. Do I have to go to runlevel 3? How do I proceed? Kostas
