unmounted filesystems accidentally
Hi all,
I accidentally unmounted filesystems using umount -a command.
How to recover from this. Please help. Thanks in advance!
when i try to use mount -a i got the following output.
Code:
[root@lnx ~]# mount -a
mount: /dev/vg00/lvol05 already mounted or /opt busy
mount: /dev/vg00/lvol07 already mounted or /u01 busy
mount: /dev/cciss/c0d0p1 already mounted or /boot busy
following is the /etc/fstab file
Code:
[root@lnx ~]# more /etc/fstab
/dev/vg00/lvol00 / ext3 defaults 1 1
/dev/vg00/lvol02 /var ext3 defaults 1 2
/dev/vg00/lvol05 /opt ext3 defaults 1 2
/dev/vg00/lvol03 /usr ext3 defaults 1 2
/dev/vg00/lvol04 /tmp ext3 defaults 1 2
/dev/vg00/lvol06 /home ext3 defaults 1 2
/dev/vg00/lvol07 /u01 ext3 defaults 1 2
LABEL=/boot /boot ext3 defaults 1 2
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
/dev/vg00/lvol01 swap swap defaults 0 0
below is the df command output
Code:
[root@lnx ~]# df -h
