Bug #1013: time-slider fails to take snapshots on complex dataset/snapshot configuration
https://www.illumos.org/issues/1013

Author: Florian Manschwetus
Status: In Progress
Priority: Normal
Assignee: OI JDS
Category: Desktop (JDS)
Target version: oi_151
Difficulty: Medium
Tags: time-slider


pool-strukture:
data (freq,hourly,daily,weekly,monthly)
data/Admin (inherit)
data/Projects (inherit)
data/PublicWWW (inherit)
data/Teaching (inherit)
data/backup (inherit, -frequent)
data/backup/images (-all, +stagingdisk-schedule)
data/backup/images/linux (inherit)
data/backup/images/windows (inherit)
data/backup/serviceDaten (inherit)

data/cvs (no snaps, -all)
data/inc (no snaps, -all)
data/scratch (no snaps, -all)
data/test (no snaps, -all)
data/users (inherit)

Problem occurred when setting e.g. com.sun:auto-snapshot:hourly from false to inherit or true (com.sun:auto-snapshot is false on data, due to explicit schedule selection)

log snippet:

Failed to create snapshots for schedule: hourly
Caught RuntimeError exception in snapshot manager thread
