Hi all,
Whilst I delve even further into the LSM documentataion, I was hoping
that someone on the list could point me in the right direction on this
one.
Setup: AlphaServer 400 4/233 with 2 internal rz26n SCSI disks (Id 0 & 1)
Digital Unix 3.2D running ASE 1.3
Configuration: root and swap are mirrored. user is also mirrored. They
are all advfs filesystems wiht their domain referencing
LSM disk group (root_dg) volumes and rootvol, swapvol and
volrz0g. A small partition (rz0d) was set-aside for
initial volsetup configuration.
The only way I found to dump the root and usr filesystem was to shutdown
to single-user mode and to vdump root (with no-rewind device) then mount
/usr and vdump it.
I was later able (on another identical computer) to boot from cd-rom,
disklabel both disks (with -t advfs) for root, make dummy /etc/fdmns
directory and links and restore the filesets. The intention was to run
through the disk mirroring procedure again.
Unfortunately you cannot boot (given the restored config), and if I
fudge other links in /etc/fdmns and re-reference /etc/fstab, I can boot,
however I am now stuck, unable to volsetup -o force (get volsetup
internal errors).
I get the feeling that I am digging myself into a deeper and deeper
hole. There must be a better way.
Any help, tips or ideas will be appreciated. Please e-mail directly to
me, and I will summarise within the next few days.
PS: In case you wonder - Why do all this. We are configuring the
computers as part of a complete solution (with our customised software).
The end-users have specified a system build from tape.
Thankyou,
