Hello,
I am still trying to install an almost brand-new amd64 machine using
FAI 3.2.20, with the following setup.
* two disks as two raid1 sets (/boot + lvm for everything else)
* /boot on md0, the rest in one big volume group
Initially, my setup-storage file looked like this:
--------------------- cut
primary - 200 - -
primary - 0- - -
disk_config sdb bootable:1
primary - 200 - -
primary - 0- - -
disk_config raid
raid1 /boot sda1,sdb1 ext2 rw
raid1 - sda2,sdb2 - -
disk_config lvm
vg uv0 md1
uv0-root / 500 ext3 rw,errors=remount-ro
uv0-swap swap 4096 swap sw
uv0-usr /usr 20480 ext3 rw
uv0-var /var 2048 ext3 rw
uv0-qmail /var/qmail 200 ext3 rw
uv0-home /home 60000- ext3 rw
uv0-var_log /var/log 1024 ext3 rw
uv0-qmail_queue /var/qmail/queue 1024 ext3 rw
--------------------- cut
After resolving a module related problem (see other thread), the
installation almost completed. I made some errors in my configuration,
though and wanted to re-run the installation, but without the two or
three hours delay that are attributable to the creation and re-syncing
of the software raid, if possible. Therefore, I changed the
setup-storage configuration file to:
--------------------- cut
disk_config sda bootable:1 preserve_reinstall:1,2
primary - 200 - -
primary - 0- - -
disk_config sdb bootable:1 preserve_reinstall:1,2
primary - 200 - -
primary - 0- - -
disk_config raid preserve_reinstall:1,2
raid1 /boot sda1,sdb1 ext2 rw
raid1 - sda2,sdb2 - -
# disk_config lvm preserve_reinstall:1,2,3,4,5,6,7,8
disk_config lvm preserve_reinstall:1-8
vg uv0 md1
uv0-root / 500 ext3 rw,errors=remount-ro
uv0-swap swap 4096 swap sw
uv0-usr /usr 20480 ext3 rw
uv0-var /var 2048 ext3 rw
uv0-qmail /var/qmail 200 ext3 rw
uv0-home /home 60000- ext3 rw
uv0-var_log /var/log 1024 ext3 rw
uv0-qmail_queue /var/qmail/queue 1024 ext3 rw
--------------------- cut
[ minor gripe: When I first tried to say this:
"preserve_reinstall:1,2,3,4,5,6,7,8", setup-storage errored out,
talking something about a syntax error. ]
With this configuration, I now get another problem that I'm unsure
about how to solve:
Starting setup-storage 1.0.5
Can't preserve /dev/md1 because it is not defined in the current config
This I don't understand because I only added "preserve_reinstall
attributes" to all partitions, but didn't really change anything.
Running "mdadm-startall" gives me the two raid partitions back,
although with errors:
installclient# mdadm-startall
W: mdadm: using ARRAYs defined in existing mdadm.conf.
Assembling MD array md0...failed (no devices found).
