zfs discuss - Jun 2008 - Oops: zfs-auto-snapshot with at scheduling

Hi all,

I''ll attach a new version zfs-auto-snapshot including some more
improvements, and probably some new bugs. Seriously, I have
tested it, but certainly not all functionality, so please let me know
about any (new) problems you come across.

Except from the change log:

  - Added support to schedule using at(1), see
    README.zfs-auto-snapshot.txt
  - take_snapshot will only run if option "manual" given or FMRI is
    online
  - added command line action "unschedule"
  - retry all jobs (at and cron) using a short term reschedule
    (AT_RETRY="now + 5 minutes") if they cant be run due to a
    temporary condition such as
    - smf service offline or uninitialized
    - pool being scrubbed
  - added command line action "list" to list configured cron and at
    jobs (mainly to get human readable information about which
    snapshot is due when)
  - added validation functions for various SMF properties

Cheers,

Nils

Just to let you know that I *have* seen your mails on this and really
appreciate getting the feedback, but I just haven''t had a chance to dig
into your code yet.  I wanted to spend time following up properly,
rather than giving you a quick (but probably un-researched!) answer :-)

  I''ll try to follow up on the list tomorrow...

	cheers,

An example from the readme does not work and fails with:

Error: Cant schedule at job: at midnight sun
