Hi, once again, unfortunately, in troubles. I hope you will excuse my little experience with linux and my
english, but I really need your help.
I'm having real troubles with my samba/wbel server, mainly a really weird behaviour. You can read if
interested, my previous post (dup2 bad file descriptor). Today this new "surprise". What happens is that
if I try to mount my /dev/md3, I succeed just once over three times. Here you can read:
[root@fbcsrvsmb01 root]# cat /proc/mdstat
Personalities : [raid1]
read_ahead 1024 sectors
Event: 4
md3 : active raid1 hde1[1] hdg1[0]
199141632 blocks [2/2] [UU]
md2 : active raid1 hda3[0] hdc3[1]
1108416 blocks [2/2] [UU]
md1 : active raid1 hda2[0] hdc2[1]
8803520 blocks [2/2] [UU]
md0 : active raid1 hda1[0] hdc1[1]
104320 blocks [2/2] [UU]
unused devices: <none>
[root@fbcsrvsmb01 root]# umount /samba/
[root@fbcsrvsmb01 root]# mount -t ext3 /dev/md3 /samba FAILS
mount: wrong fs type, bad option, bad superblock on /dev/md3,
or too many mounted file systems
[root@fbcsrvsmb01 root]# mount -t ext3 /dev/md3 /samba FAILS
mount: wrong fs type, bad option, bad superblock on /dev/md3,
or too many mounted file systems
[root@fbcsrvsmb01 root]# mount -t ext3 /dev/md3 /samba SUCCESS
[root@fbcsrvsmb01 root]# mount -t ext3 /dev/md3 /samba
mount: /dev/md3 already mounted or /samba busy
mount: according to mtab, /dev/md3 is already mounted on /samba
[root@fbcsrvsmb01 root]# umount /samba
[root@fbcsrvsmb01 root]# mount -t ext3 /dev/md3 /samba FAILS
mount: wrong fs type, bad option, bad superblock on /dev/md3,
or too many mounted file systems
[root@fbcsrvsmb01 root]# mount -t ext3 /dev/md3 /samba FAILS
mount: wrong fs type, bad option, bad superblock on /dev/md3,
or too many mounted file systems
[root@fbcsrvsmb01 root]# mount -t ext3 /dev/md3 /samba SUCCESS
What's the meaning of it? I made one partition, type fd, then 'mk2efs -j' each of the two drives (hdg and
hde). Then mkraid /dev/md3 it took me a lifetime to make it (200Gb - 300minutes), and what I get is that
weird thing.....I'm really confused. Should I mke2fs -j /dev/md3 before mounting? It doesn't sound
reasonable.
I'm trying to move part of the servers from win2k to linux, but now this last 2 days really twisted my
brain....
If anyone could help me undestand the reasons of what happened I would greately appreciate it.
Thanks for your time
Simone
PS would you use reiserfs?
