Re: Holding disks and the disk output driver

Brian,
I don't know much about the rait driver. Hopefully someone more knowledgeable
on the list will respond. I was unclear what you meant about moving to "diskless
backups"...

Ted,
Steve,
Amanda users,
Stupid question, how smart is the rait driver for disk ?
If you put the spool area on the output disk will it juggle
the space ok ? Will it know to move the file from one directory
to another (move the file pointer # mv perhaps) rather than
having to copy all the bits and then remove the original ?
I only ask because someone at my site is looking to move to
diskless backups...
thanks,
Brian
Ted,
I've been using a 2 TB disk array for the past month or so and it's been
working great for me without a holding disk. Using a holding disk will
require more free disk space plus the additional time to transfer from
the holding disk to the backup disk.
I recommend getting a patch from Jean-Louis Martineau
(martinea AT IRO.UMontreal DOT CA) which prevents a client error from forcing
Amanda to go into degraded mode. When Amanda operates in degraded mode,
it will only write to the holding disk, which in my case doesn't exist.
But the patch prevents client-side errors from putting Amanda into
degraded mode which allows my backups to continue being written to the
backup disks.

If you're using the disk output driver to run backups to a large disk
array, is there any reason to use a holding disk?
