Current Installation: CentOS 7.1503 with SerNet Samba 4 ver. 4.1.17
configured as Active Directory Domain Controller.
Current Installation: HP Workstation with dual Xeon quadcore cpu's and 4 x
SATA hard drives NOT configured in RAID array.
New Installation: CentOS 7.1503 minimal install
New Installation: SuperMicro with single Xeon quadcore cpu and 4 x SATA
hard drives configured in two pairs of RAID 1.
The Current Install is about 3.5 GB's and has my Samba 4 setup all solid
and working well. I want to know if it's possible to simply:
- tar up the whole root partition
- put it on a USB drive
- boot the New server with a livecd
- chroot into / partition
- unpack the tar'ed root (/) from the USB drive into the New server root
(/).
Both installs used the automatic partitioning from anaconda, so /boot is on
a separate partition. Each server has an initrd and kernel that works from
/boot partition. Both CentOS installs are setup using the xfs filesystem
on the root (/) partition.
I saw someone do this successfully once but they left out certain
directories like /srv , /tmp , and /var.
But I'm not 100% certain which directories need to be left out of the
tarball.
Has anyone done this before?
Do you know if it's doable?
Thanks for reading.
