Help with Solaris file system
Hi,

I have not worked on Solaris 10 that much. Need some help with this. I can't seem where the file or how the file systems are mounted. Please see the /etcvfstab below.

Code:
more vfstab
#device         device          mount           FS      fsck    mount   mount
#to mount       to fsck         point           type    pass    at boot options
#
fd      -       /dev/fd fd      -       no      -
/proc   -       /proc   proc    -       no      -

/devices        -       /devices        devfs   -       no      -

objfs   -       /system/object  objfs   -       no      -
swap    -       /tmp    tmpfs   -       yes     -

I don't know what rpool means? How is the root file systems getting mounted. This server needs to be moved, I am trying to do ufsdump on / and I can't seem to figure out how to do.

Please help.

Looks like you are using ZFS.

To see what ZFS pools you have:
Code:
# zpool list

To see what ZFS filesystems you have:
Code:
# zfs list

This is what I see...

Code:

NAME SIZE ALLOC FREE CAP HEALTH ALTROOT
pool5 808G 552G 256G 68% ONLINE -
rpool 136G 20.9G 115G 15% ONLINE -

pool5 555G 240G 21K none
pool5/sybase 1.85G 3.15G 1.85G /usr/sybase
pool5/sybdata 550G 240G 550G /sybdata
rpool 42.5G 91.4G 97K /rpool
rpool/ROOT 10.0G 91.4G 21K legacy
rpool/ROOT/solaris10u9 4.93G 5.07G 4.93G /
rpool/dump 16.0G 91.4G 16.0G -
rpool/data 30.5K 91.4G 30.5K /data
rpool/swap 16.5G 108G 16K -

since I am using ZFS. can you advise how to do backup of root. I never used ZFS before, I will do some reading, just wondering if you know how the backup works under ZFS.

Thank you so much.

Have a look to the "ZFS Root Pool Recovery" chapter in the ZFS troubleshooting guide.
