[OpenIndiana-discuss] time-slider is snapshotting swap and dump after upgrading to oi_147

[Jeremy Thornhill]

Hello list,

I've encountered a bizarre situation with time-slider on OI 147. As
background, this is a x86 system that's been upgraded from OpenSolaris
snv_133, and the time-slider configuration I'm using is unmodified
post-upgrade (save for disabling the legacy time-slider-cleanup cron
job).

What I see is that rpool/swap and rpool/dump - which are both
configured with 'com.sun:auto-snapshot = false' - are being
snapshotted at every possible interval. Additionally, it seems that
time-slider is not ever cleaning up these snapshots, even when they
have a "USED" value of 0. This results in hundreds of empty snapshots
being created which I've had to manually remove. Auto snapshots for
other filesystems, however, seem to be both created and destroyed as
expected; indeed, I have other filesystems with 'com.sun:auto-snapshot
= false', and they are not being snapshotted.

Does anybody have an idea of what's going on, or how I can work around
this? I've upgraded all pools and volumes and I'm really not sure what
the issue here could be. I even fired up the time-slider-setup gui for
kicks, but it seems hard coded to ignore swap and dump entirely, as
they weren't visible at all in any of its options.

Thanks,
Jeremy
