Hi there A couple of months ago I was happily running dm-crypt on my root partition under FC6 for several weeks (would have been kernel 2.6.18-2.6.19), and then over a period of a few days had entire directories disappear and finally massive file system corruption (ext3 on top of dm-crypt on top of IDE disk in my Dell laptop). I decided it must have been a hardware problem and got my disk replaced. And took the opportunity to upgrade to FC7. For several weeks I ran with no problems - without encryption. Then I backed it up, dm-crypt'ed the root partition and restored and away I went. Now 2 weeks later and suddenly I'm getting kernel errors about ext3 corruption - and am loosing files again!

The disk showed no problems when unencrypted, I have run memtest86+ (via booting off it,etc) with no signs of bad RAM. I mean it could be the disk controller I suppose, but I have found several articles showing similar problems with dm-crypt in the past, so I am wondering if this is actually a software issue instead... Are there any outstanding issues with dm-crypt that could explain this behaviour? FC7 running 2.6.21-1.3228.fc7 and cryptsetup-luks-1.0.3-4.fc7 Thanks Jason --------------------------------------------------------------------- dm-crypt mailing list - http://www.saout.de/misc/dm-crypt/ To unsubscribe, e-mail: dm-crypt-unsubscribe@xxxxxxxx For additional commands, e-mail: dm-crypt-help@xxxxxxxx
