Otherwise, your only feasible option is to restore from backup.

There are probably companies you can go to who will do this for a non-trivial fee, but if you want to do it by hand, I've found that reasonable progress can be made, especially if the files are text-only and small. The first thing you want to do is make sure that you don't mount the file system writable -- you don't want to create any situation where the storage might be written to. One example might be if you crash the box with it writable, and bgfsck creates a snapshot of the disk during the check. Usually at this point I'd take a snapshot of the file system, especially if small, by dd'ing the entire partition to a file on another storage device. There are a number of ways you can proceed from here, but to be honest, the first thing I'd try, especially if there wasn't a lot of other random data on the file system, is to run strings on the image. strings takes a byte stream and pulls out contiguous sequences of textish ascii characters--because of how we encode e-mail, e-mail qualifies as a very long sequence of such characters. Unfortunately, they will turn up in the order the data appears on the disk, and will also include non-delete files. A reasonable next refinement would be to try to run strings on only the free blocks, rather than all blocks, which while also non-perfect, will carefully exclude real data on the file system. I'm not sure if we have an easy way to select down to those blocks, unfortunately, but writing a tool to identify free blocks and dump them sequentially to a file probably isn't all that hard. Programs like fsck will already have the routines necessary to identify all reachable blocks, as a starting point. Perhaps someone on the list has such a tool already, or an idea about how to use existing tools?

In /usr/ports/sysutils/tct you will find "The Coroners Toolkit" Lazarus is part of that program. Do NOT confuse it with lazarus in the editors. You need to unmount what you have so you don't lose any more files. Lazarus will go ahead and recover only blocks with data, which makes it nicer than dd which will take everything off the disk including unused blocks. The data will be saved in sets of files which can be viewed in HTML, or read directly with editors. You need some space to put the data ON ANOTHER FILESYSTEM - or on another drive - as you can't put it on the drive you are trying to recover - as you will over-write the data you are trying to get. I don't even recall if it will let you do that. It is not a newbie program. It was written by Wietse Venema and Dan Farmer. The program in the ports is 1.16. So you probably want to go to http://www.porcupine.org/forensics to get 1.18 SO it's not really in the ports anymore - I just checked.

I'm currently having a problem where mysqld gets stuck in "zfs" state and it becomes completely unusable and unkillable. The machine generally works, but cannot be rebooted from the OS in this case (it must be manually power-cycled). I think a (possibly long-ish) stress test on a multi-CPU machine (my own is only dual, but has a relatively big uptime) with both reading and writing via mysqld might ferret out a problem with concurrency.

I had an unkillable MySQLd a while ago that required reboot (pre-RELENG_7=20 CURRENT). It was in uninterruptable sleep, but I can't swear to whether it= =20 was in zfs state. This was on a quadcore core 2 duo. I can do some sysbenching on a dual core machine with and without ZFS, but = it=20 sounds like that won't be more useful than what you already have available. =2D-=20 / Peter Schuller PGP userID: 0xE9758B7D or 'Peter Schuller ' Key retrieval: Send an E-Mail to getpgpkey@scode.org E-Mail: peter.schuller@infidyne.com Web: http://www.scode.org --nextPart2135690.ajQ7k9PUjr Content-Type: application/pgp-signature;
