Package: linux-image-2.6.24-etchnhalf.1-486 Version: ?
Hello, I have an extra-ordinary problem or perhaps an Kernel bug: My Server: * Debian Etch (Kernel: Etch-n-half), Samba 3.0.24 * 500gb harddisk with a system and a data partition. Both are crypted with Luks (cipher:serpent-cbc-essiv:sha256) * Raid 5 crypted with Luks (cipher: serpent-cbc-essiv:sha256) * All partitions have the ext3 filesystem Client1: Notebook (Windows XP and Fedora) Client2: Desktop (Fedora) I did all tests from both clients My problem: I tried to copy RAW pictures (*.cr2 files) from a client to the raid5 partition with the following 4 different ways. 1. I exported the raid partition with samba and copied the pictures with Windows XP and the Windows Explorer 2. I copied the pictures through an smb-mount with Fedora with the "cp"-command 3. I copied the pictures with the "scp"-command (first initiiated from the client and then from the server) 4. I copied the pictures with the "rsync"-command (first initiiated from the client and then from the server) I checked the files after I had copied them with "md5sum" and I saw that the values where different to the values of the original files. The pictures where broken. They had lila stribes and where cutted in the half. I tried the same 4 methods and copied the pictures on the 500gb data partition and there where no failures or md5sum differences. Then I copied the pictures in an ssh shell with an normal cp-command from the local-partition to the raid5-partition. The md5sum values where the same, so this worked well. So in my opinion the problem has to do with the crypted raid5. I tried to reproduce this failures with other files but i had this problem only with RAW (*.cr2 Canon) picture files. I tried to repair my system with these 3 Methods: 1. fsck.ext3 -y /dev/mapper/md0_crypt 2. fsck.ext3 -c -p /dev/mapper/md0_crypt 3. server rebooted a few times I couldn't find out any failure messages in the log-files or at the booting. After many hours I found this out: With Kernel 2.6.24-etchnhalf.1-686, Kernel 2.6.24-etchnhalf.1-486 and Kernel 2.6.26-bpo.1-486 I could reproduce my Image-copy-problem. As I booted the older Kernel 2.6.18-6-486 I where able to copy the pictures with any of the methods above and the md5sum values where OK. Because of this I think its an Kernel problem. I absolutly don't know what additional information I should post with this E-Mail, please write me what I should add or where I should post the extra-information. Sorry if I addressed this E-Mail wrong, I don't know where to go with this problem/bug. With bug-buddy I weren't able to make a Bug-Report.
