 |

I walked a friend through a gentoo install since he was being kind enough to install gentoo on the box and let me use it as a backup server... anyways... some files I was doing the config for him and would have him wget it from me... one of these such files was the fstab... but instead of saving as fstab, it saved as fstab.1
Now since I wasn't in front of the box (in fact it's several hundred miles away) I didn't notice this until now... the server's been up and running a few days now, and I do a df -h to see how much space there is and notice there is only 10 GB showing up on a 60GB hard drive.... umn... so I do a mount:
| Code: |
/dev/ROOT on / type xfs (rw,noatime)
proc on /proc type proc (rw)
none on /dev type devfs (rw)
tmpfs on /mnt/.init.d type tmpfs (rw,mode=0644,size=2048k)
tmpfs on /dev/shm type tmpfs (rw)
|
now I *know* this kernel doesn't support XFS, and the proof of that is a simple cat /proc/filesystems:
| Code: |
nodev rootfs
nodev bdev
nodev proc
nodev sockfs
nodev tmpfs
nodev shm
nodev pipefs
nodev binfmt_misc
ext3
ext2
nodev ramfs
iso9660
nodev devfs
nodev autofs
|
so my questions are>
1. What is the root partition mounted as (is my assumption of ext2 correct?)
2. If I fix the fstab and reboot, will the partition be alright?
side note: they were originally mke2fs -j..
can I safely mount it as ext3? or should I recreate the journal first?
Thanks!

mke2fs -j == ext3 , u mount ur partition accordint to ur "mk"  keep in mind when u first edit /etc/fstab ... whatever u see there , are all diff examples , and i know it could be confusing good luck  |

yes, I'm fully aware that the -j mean ext3... but if the kernel has automounted it has ext2 (if my assumption that it fell back on that is true), then does the journal need to be remade, or is it safe to mount a partition as ext3 after it's been mounted and written to as ext2?
[wow long run on sentence, does it make any sense? my English sucks and I grew up in the USA... that's public schools for ya]

ok, I fixed the fstab (mv /etc/fstab.1 /etc/fstab) and rebooted... and everything seems to be working perfectly so far (only been back up for about 20 minutes or so though.......). working on copying all the data to their correct partitons now....
just FYI for anyone else who finds them in this situation....
1. The kernel autodetected that the root partition was ext2 compatible and did mount it as ext2
2. ext2 and ext3 are compatible enough that you can mount a partion ext2 and write to it and still have it work successfully mounting it as ext3 and using it.
