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?
