mount command
Hello friends!
Today I have a problem with mounting the filesystem: # mount /dev/mapper/fujitsu_test /u01 mount: you must specify the filesystem type # mount -t ext4 /dev/mapper/fujitsu_test /u01 mount: wrong fs type, bad option, bad superblock on /dev/mapper/fujitsu_test, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so Can anybody help me? |
Maybe it's not ext4 - unless you're sure of that try some other formats.
|
Maybe to obvious but is fujitsu_test already formatted to a specific FS?
|
This filesystem was workable earlier. (It is my test system, on production system same filesystem mounted as ext4, so I decided that test filesystem is ext4 too.)
I founded something: # ls -l /dev/disk/by-id|grep -i #my_uuid# lrwxrwxrwx. 1 root root 10 Nov 1 16:18 dm-uuid-mpath-#my_uuid# -> ../../dm-2 lrwxrwxrwx. 1 root root 9 Nov 6 14:23 scsi-#my_uuid# -> ../../sdh lrwxrwxrwx. 1 root root 9 Nov 6 14:23 wwn-0x#my_uuid# -> ../../sdh # mount -t ext4 /dev/dm-2 /u01 mount: wrong fs type, bad option, bad superblock on /dev/mapper/fujitsu_test, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so # mount -t ext4 /dev/sdh /u01 mount: /dev/sdh already mounted or /u01 busy # fuser -c /dev/sdh /dev/sdh: 2336 # ps -ef | grep 2336 root 2336 1 0 Nov01 ? 00:00:44 /sbin/multipathd what is it? |
Is it a raid or LVM partition? What do you mean by same filesystem on production system? Is it a cloned partition?
|
It's not clone, but long time ago two servers were created similarry.
This disk is not in lvm. |

@applehalf: Are you sure /dev/mapper/fujitsu_test isn't part of LVM/Raid?
What does pvdisplay show? Also, what is the output of ls -l /dev/mapper/ and dmsetup ls |

It seems that /dev/mapper/fujitsu_test has been part of LVM/Raid (or it is, but not set-up/implemented correctly):
lrwxrwxrwx. 1 root root 7 Nov 1 16:18 fujitsu_test -> ../dm-2 fujitsu_test (253, 2) However, I'm not sure how this happened or how to restore it to the original setup. |
OK, than the right way will be to format my disk and create new volume group.
Thank you. |
