Hi,
sorry for the lame questions ahead; I've never used clonezilla before and
I'd like to get some info in advance. (I did browse the FAQ and the rest
of the website first.)
I have to transfer the contents of a single source disk to another disk:
# lsblk -o NAME,FSTYPE,MOUNTPOINT,LABEL,SIZE,TYPE /dev/sda
NAME FSTYPE MOUNTPOINT
LABEL SIZE TYPE "FSAVAIL"
sda
465.8G disk
|-sda1 ext3
RHEL5-64-/ 20G part 15G
|-sda2 LVM2_member
300G part
| |-VolGroup0-VG0swap (dm-0) swap [SWAP]
8G lvm
| |-VolGroup0-VG0home (dm-1) ext3 /home
64G lvm 51G
| |-VolGroup0-VG0varlibxen (dm-2) ext3
128G lvm 53G
| |-VolGroup0-VG0varliblibvirtimages (dm-3) ext3
/var/lib/libvirt/images 50G lvm 44G
| `-VolGroup0-VG0filestore (dm-4) ext3 /filestore
VG0filestore 50G lvm 31G
|-sda3 ext3
RHEL5-32-/ 20G part 13G
|-sda4
1K part
|-sda5 ext3 /
RHEL6-64-/ 19.1G part 13G
|-sda6 ext3
RHEL6-32-/ 19.1G part 14G
|-sda7
19.1G part
`-sda8
19.1G part
There's about 51G free space (unpartitioned) at the end of the drive.
The "FSAVAIL" column was added manually by yours truly, using "df -h".
sda7 and sda8 are Linux partitions, but unformatted.
(1) Is this layout fully supported by Clonezilla Live 1.2.12-60? (I intend
to use the Debian-based stable release). Does it matter if a logical
volume is "linear" (ie. one contiguous chunk in a PV) or not?
(2) How much space am I going to need approximately, before compression? I
reckon Clonezilla will copy the partitioning / LVM metadata, and the
non-free blocks in the ext3 filesystems I have. So about 136 GB in total.
Does that seem correct?
(3) I'd like to specify a non-default compression method, eg. pigz. Where
do I pass the "--smp-gzip-compress" option?
(4) The receiving end will be an adjacent SSH server. Can I make sure,
from the Clonezilla side, that the ssh connection itself won't use
compression or a CPU-hungry cipher? (aes128-cbc is good for me, for
example.) I could do this on the Clonezilla side, by editing
"$HOME/.ssh/config" before the ssh connection is started. Is this
supported?
(5) After the backup process finishes, can I somehow verify the archive's
integrity / completeness (without a full restore)? The source disk will be
irrevocably gone at "real restore" time.
Thank you very much,
Laszlo
