http://www.linuxquestions.org – Right, I almost royally messed up my server by trying to create a reiser filesystem. I had to change the etc/fstab on reboot as it was failing. This has removed the /home label on the /dev/sda2 partition. fdisk -l gives: Quote: [root@ sysconfig]# fdisk -l Disk /dev/sda: 250.0 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 10 80293+ 83 Linux /dev/sda2 11 29061 233352157+ 83 Linux /dev/sda3 29062 29698 5116702+ 83 Linux /dev/sda4 29699 30401 5646847+ 5 Extended /dev/sda5 29699 30335 5116671 83 Linux /dev/sda6 30336 30400 522081 82 Linux swap / Solaris [root@ sysconfig]# df -h gives the following but it is missing sda2 Do I have to remount it or something? I then want to install reiser on the /dev/sda2 and relabel /home. I intend to have my squid cache on this drive also. Quote: [root@ ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda5 4.8G 1.5G 3.0G 34% / /dev/sda3 4.8G 1.7G 2.9G 37% /var /dev/sda1 76M 23M 50M 32% /boot tmpfs 465M 0 465M 0% /dev/shm [root@serve ~]# EDIT: I successfully ran reiserfs on the partition but it will not now recognise the filesystem when trying to mount it. Quote: [root@serve ~]# mkfs.reiserfs /dev/sda2 mkfs.reiserfs 3.6.19 (2003 www.namesys.com) A pair of credits: The Defense Advanced Research Projects Agency (DARPA, www.darpa.mil) is the primary sponsor of Reiser4. DARPA does not endorse this project; it merely sponsors it. Jeremy Fitzhardinge wrote the teahash.c code for V3. Colin Plumb also contributed to that. Guessing about desired format.. Kernel 2.6.18-164.11.1.el5 is running.

ALL DATA WILL BE LOST ON '/dev/sda2'! Continue (y/n):y Initializing journal - 0%....20%....40%....60%....80%....100% Syncing..ok Tell your friends to use a kernel based on 2.4.18 or later, and especially not a kernel based on 2.4.9, when you use reiserFS. Have fun. ReiserFS is successfully created on /dev/sda2.
