zfssnap reports trying to delete pools

[mlindgren80]

Here is the output that gets mailed to me:

Scrubbing of zfs pools:
   starting scrub of pool 'ssdmirror':
      consult 'zpool status ssdmirror' for the result
   starting scrub of pool 'usbenc':
      consult 'zpool status usbenc' for the result
   skipping scrubbing of pool 'zfsbak':
      last scrubbing is 29 days ago, threshold is set to 30 days
   skipping scrubbing of pool 'zfsraid2':
      last scrubbing is 29 days ago, threshold is set to 30 days
   starting scrub of pool 'zroot':
      consult 'zpool status zroot' for the result
FATAL: trying to delete zfs pool or filesystem? WTF?
  This is bug, we definitely don't want that.
  Please report it to https://github.com/graudeejs/zfSnap/issues
  Don't panic, nothing was deleted :)

And here is my config:

daily_zfsnap_enable="YES"

daily_zfsnap_delete_enable="YES"

daily_zfsnap_fs="zfsraid2/shows zfsbak/movies"
daily_zfsnap_flags="-s -S"
daily_zfsnap_verbose="YES"
daily_zfsnap_delete_flags="-s -S"
daily_zfsnap_delete_verbose="YES"


daily_scrub_zfs_enable="YES"
daily_scrub_zfs_zroot_threshold="7"
daily_scrub_zfs_ssdmirror_threshold="7"
daily_scrub_zfs_zfsbak_threshold="30"
daily_scrub_zfs_usbenc_threshold="14"
daily_scrub_zfs_zfsraid2_threshold="30"

As stated in the email output, it told me to report the issue, so here I am :) I am running FreeBSD 10.1 with its associated ZFS version.

hi, I'm hitting this bug too, and it's not clear why. It's a scary error message, so can someone explain more what's happening .. Thanks!

[graudeejs]

Execute this and post output:

 zfSnap -zpool28fix -n -d -p 'hourly-' -p 'daily-' -p 'weekly-' -p 'monthly-' -p 'reboot-'

And then execute this and post output

sh -x /usr/local/sbin/zfSnap -zpool28fix -n -d -p 'hourly-' -p 'daily-' -p 'weekly-' -p 'monthly-' -p 'reboot-'

Note: I think you're missing -zpool28fix flag in daily_zfsnap_delete_flags. Not that it should cause this misbehavior, but still.

@graudeejs .. The first command returns nothing .. The second one returns http://fpaste.org/250760/

Thanks for helping!

Weird, 1st command should return list of zfs commands
Something like:

$ zfSnap -zpool28fix -n -d -p 'hourly-' -p 'daily-' -p 'weekly-' -p 'monthly-' -p 'reboot-'          
/sbin/zfs destroy d/FreeBSD/10r1p5_custom@2015-07-28_20.07.12--5d
/sbin/zfs destroy d/FreeBSD/current@2015-07-28_20.07.12--5d
/sbin/zfs destroy d/FreeBSD@2015-07-28_20.07.12--5d
/sbin/zfs destroy d/home/graudeejs/archive@2015-07-28_20.07.12--5d
/sbin/zfs destroy d/home/graudeejs/photo@2015-07-28_20.07.12--5d
/sbin/zfs destroy d/home/graudeejs/videos@2015-07-28_20.07.12--5d

I ran it like 5 times .. nothing at all

[graudeejs]

Try latest version from legacy branch, I added few lines in order to see what exactly caused an error.
17b1f38

Try with this one: https://raw.githubusercontent.com/zfsnap/zfsnap/17b1f389365a57f04448c0800cde327d47baa02e/zfSnap.sh

run:

./zfSnap.sh -zpool28fix -v -d -p 'hourly-' -p 'daily-' -p 'weekly-' -p 'monthly-' -p 'reboot-'

This will try to delete snapshot, and If you get that error, we should see why exactly.

[graudeejs]

Btw, @kim0, are you using FreeBSD as well?

[kim0]

@graudeejs Yes I'm on freebsd 10.1 ... I'll try that version next

[graudeejs]

@kim0, Any news?
