Dea Bareos users.
I want to use (if possible) multiple disk filesystems for Storage. I
understand that it's possible to do this by making each filesystem its own
Device and giving each it's own name.. then I can manually divide jobs among
storage. But I was wondering if I can assign multiple devices to the same
Storage or same Pool and have Bareos automatically find an available volume on
any device and use it...
I searched previous questions and found this email quoted below from several
years ago, showing that Bareos will select the first device with free space.
But it causes problems when trying to restore...
Has any work been done on this in the last few years to make this work better?
Ideally I want bareos to just full up all my disks with volumes and use them as
needed and as available and keep track of what was stored where... but if that
is not possible then we are looking at using ZFS to make one huge device. But
ideally we would prefer not to.
Thanks
Ben
