This RAID0 volume was for scratch purposes, so that it is fast and vast. I just was not prepared to see a disk fail only a month after I got it :-) But now I know better. The data there was not that critical, I could have let it go ... > I consider you lucky to have gotten back as much > data as you did, but > I'd also worry that your remaining data is suspect, > esp since fsck > just checks the meta-data of the filesystem, but > does nothing to check > whether the data inside various files is actually > any good.

I did a check on the volume before I copied it via "find '*' |xargs cat > /dev/null" or something like that, and few files had unreadable sections, I took note of them. The most frequently written sectors on disk were failing over time, but in read-only mode the drive appeared to be stable. Also, when I "dd"ed it to a new drive, I got a list of bad sectors and I knew the filesystems they were under. So I hope this business is under control. > Just my two cents, from a man who runs a pair of > mirrored 120gb HD for > his /home and /local volumes. It is still a trade-off. Is one prepared to do a bit of work to recover volatile data, or should EVERYTHING be mirrored? I guess since even minor recovery can cost quite a bit of time, having total duplication can be appropriate. On the other hand, there is a whole bunch of other things which also take time for recovery (like the OS going south), so where does one draw the line?
