An excellently told tale Jeb! I know it's bit late to ask but do you perchance have any snapshots available?
And it's always worth asking if you have any of your lost files squirrelled away elsewhere, or have a means to recreate them - anything which can reduce the size of the disaster is good news. Wishing you luck! On 14 Oct 2015, at 4:39, Jeb Winders wrote:
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
