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. -jeb ------------------------------------------- smartos-discuss Archives: https://www.listbox.com/member/archive/184463/=now RSS Feed: https://www.listbox.com/member/archive/rss/184463/25769125-55cfbc00 Modify Your Subscription: https://www.listbox.com/member/?member_id=25769125&id_secret=25769125-7688e9fb Powered by Listbox: http://www.listbox.com
