I think it is a quite serious issue. since we know people are using it successfully since over a year in not too small production environments, I'm very confident that whatever weirdness you see is not drbds fault. 1. make sure you use at least 8K stack size in your kernel. 2. make sure you use a 18.104.22.168 or later kernel. (the bio-clone data corruption issue) 3. make sure you use recent lvm and xfs and whatnot tools. > The attachment is the kernel messages. Any helps and suggestions are welcome. sorry, no time for that, right now... but one thing is strange from a glance: sometimes I see > XFS mounting filesystem drbd1 ^^^^^^^ then I see > XFS mounting filesystem dm-5 ^^^^^^ and I recommend to explicitly specify the file system type, to avoid mounts guessing heuristics: > FAT: Unrecognized mount option "usrquota" or missing value cheers, -- : Lars Ellenberg Tel +43-1-8178292-0 : : LINBIT Information Technologies GmbH Fax +43-1-8178292-82 : : Schoenbrunner Str. 244, A-1120 Vienna/Europe http://www.linbit.com : __ please use the "List-Reply" function of your email client.
