Hello All,

First let me say that I greatly appreciate the work the community and
joyent have done on smartos.  I am a big fan.

I know that my subject may seem provocative and I don't really mean it that
way, but on the other hand my files seem to be gone so maybe a smidge of
provocation is in order.

I do things that I probably should not like running the 2012Q2 release
since, well second quarter 2012.

When I started using smartos I had big plans to do all the zones stuff I
used to do on sol10 and opensolaris but one thing led to another and I
ended up mostly just running a zfs fs in the global zone as a place to dump
files until I made time to really get into it.

Well this past weekend the time finally came.   After much investigation
and trial and error, I figured out that I had goobered up the old
smartos64plus zones I had made previously.  Instead of trying to fix them I
went ahead and downloaded the latest usb image so I could get with the
modern age, be on the cutting edge, right side of history, all that stuff.

While I was waiting for things to 'dd' I rearranged some of the files and
dirs in my global zone zfs fs to kill time and then got to rebooting.

I then ran into the whole 'zones/dump' pool degraded issue but I eventually
find the guy who documented destroying and remaking the dump zfs and things
were undegraded again.

I made a working zone , got some stuff from pkgin, everything was going
swimmingly.

I mention all of the above to illustrate that smartos and I had a big
weekend.

Then I went to retrieve some files from my old global zone zfs filesystem
and all but two of the directories there were gone.  Specifically
everything but the dirs I had been rearranging were gone.

10 points to whomever has already figured out what happened

At first I thought there was some kind of zpool something or other
happening cause I had just gotten over that whole 'degraded' scare the day
before.  But zpool stuff doesn't usually leave some files intact and
visible and the fs mounted.

Here is a hint -- back in 2012 when I made this fs to dump files into I
obviously could not call it zones/dump because that was already taken.  so
the next best thing I could think of that was not in use already was ...
wait for it ... zones/archive

5 points if you get it now.

For those of you still reading, evidently zones/archive is an actual thing
now and there is a handy cron job in the root crontab to find everything in
there which has not been touched in 7 days and 'rm' it.

so my dir full of linux iso's avoided certain doom, for now.  but
everything else got 'rm'd

I realize this is an edge case and I shouldn't be putting stuff in the
global zone in the first place but if anyone has any advice for undeleting
files from zfs I would greatly appreciate it.

I wanted to learn more hardcore OS and filesystem stuff so I guess I get my
wish :)

Another question -- should I rename my zfs fs zones/archive to something
else or would that make it harder to recover stuff ?

or am I just deluding myself to think there will be any recovery ?

Thanks for any help you can render.  In the mean time I will make a shell
script to touch the dirs in zones/archive everyday.

And let my story serve as a caution to any wayward soul who would make a
filesystem in the global zone.
