[zfs-discuss] Time-slider - zfs auto-snapshot services transition to maintenance?
heya,
I'm using OpenSolaris 2008.11 (101a), and trying to use the time-slider
functionality.
The SUNWgnoem-time-slider and SUNWzfs-auto-snapshot packages enabled, and I've
enabled time-slider via System, Administration, Time-Slider Setup.
However, the auto-snapshot services appear to go into maintenance when they try
to make their snapshots, and the time-slider service then goes into offline.
I've included some log output below, which should hopefully provided some more
info.
Cheers,
Victor
