| |
Hi all, to make short a long story: a) five pata disks Maxtor 500GB each one; b) one big software raid 5 (/dev/md1);[1] c) dmcrypt-ing /dev/md1;[2] d) after 500GB copied I've got fs corruption;[3]
vanilla kernel, well tested hardware,[4] debian testing (to have dm-crypt). I'm using same configuration (md+dm-crypt+ext2/3) on other server, without problem, from years. It's first time I use it on big partitions (1.9TB), sure there are situations with much bigger storage, and it's first time I've got problems. So: a) is anybody outthere using this kind of configuration with success? b) what can I do to debug the problem? I've spent last weeks working on hardware (dell servers mostly), to be sure to avoid hardware problems; c) has someone (OSDL?) regression tests on md+dm-crypt?
Thanks a lot for your time, gelma

I can see the problem with ext2/ext3/reiserfs. [4] memtest and so on. I also tried the same box of disks on totally different hardware, with same results. changed from ATA cable to RAM. I tried also different IDE controller (the one on motherbords, old HPT 370/372, new HPT 302). - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
