Hi all,
Excuse the question as I'm sure those more experienced will find it simple.
I've a CentOS5.1 box with six physical drives, two of which are used for
nightly rsync
backups. Contents of /etc/mtab, /etc/fstab, df and a brief narrative
follow:
======================================================
# cat ./fstab
/dev/VolGroup00/LogVol00 / ext3 defaults 1 1
LABEL=/home /home ext3 defaults 1 2
LABEL=/home/adminusers /home/adminusers 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/VolGroup00/LogVol01 swap swap defaults 0 0
======================================================
# cat ./mtab
/dev/mapper/VolGroup00-LogVol00 / ext3 rw 0 0
proc /proc proc rw 0 0
sysfs /sys sysfs rw 0 0
devpts /dev/pts devpts rw,gid=5,mode=620 0 0
/dev/sdc1 /home ext3 rw 0 0
/dev/sdd1 /home/adminusers ext3 rw 0 0
/dev/sda1 /boot ext3 rw 0 0
tmpfs /dev/shm tmpfs rw 0 0
none /proc/sys/fs/binfmt_misc binfmt_misc rw 0 0
sunrpc /var/lib/nfs/rpc_pipefs rpc_pipefs rw 0 0
======================================================
# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
131G 4.7G 120G 4% /
/dev/sdc1 271G 147G 111G 58% /home
/dev/sdd1 271G 3.9G 253G 2% /home/adminusers
/dev/sda1 99M 20M 74M 22% /boot
tmpfs 442M 0 442M 0% /dev/shm
======================================================
Each night, in addition to our tape backup paradigm, an rsync script is
run which mounts /dev/sdb1 on /mnt/sysinfo and copies system data from
sda1 there. /dev/sdb1 is a 146GB drive. The script then mounts
/dev/sde1 on /mnt/userdata for a copy of /home and /home/adminusers.
/dev/sde1 is a wholly underutilized 300G drive.
I'd like to move the contents of /home/adminusers from /dev/sdd1 to
/dev/sdc1 and use that underutilized drive elsewhere. What's the least
invasive way of doing this given the hardware and partitioning on my system?
Thanks in advance,
-Ray
