Hello all.. I'm making some tests with iozone running on a Linux (initiator), writting on a solaris target (ZVOL). I think there is a BUG in Linux initiator software (open-iscsi), but i just want your opinion, to see if the target can be the problem. Seems to me like a corruption in the filesystem metadata (client is not syncing writes ?). The REISER filesystem seems to be more robust, and can survive the fails (i'm unmounting the FS between tests). Trying to use the XFS filesystem, in the middle of the tests i got: ... sd 9:0:0:0: rejecting I/O to offline device sd 9:0:0:0: rejecting I/O to offline device sd 9:0:0:0: rejecting I/O to offline device sd 9:0:0:0: rejecting I/O to offline device sd 9:0:0:0: rejecting I/O to offline device sd 9:0:0:0: rejecting I/O to offline device sd 9:0:0:0: rejecting I/O to offline device sd 9:0:0:0: rejecting I/O to offline device sd 9:0:0:0: rejecting I/O to offline device xfs_force_shutdown(sda1,0x1) called from line 338 of file fs/xfs/xfs_rw.c. Return address = 0xc026e66e Filesystem "sda1": I/O Error Detected. Shutting down filesystem: sda1 Please umount the filesystem, and rectify the problem(s) xfs_force_shutdown(sda1,0x1) called from line 338 of file fs/xfs/xfs_rw.c. Return address = 0xc026e66e ...
I did try many times with no luck... so i did try with the EXT3 filesystem (maybe a XFS bug), and the same problem (i do not have the EXT3 error, sorry). And after the error, the Linux can't mount the filesystem anymore, because the device (/dev/sda) is lost. After that i need to recreae the filesystem... Now i'm running the tests with REISER, and seems to be working, but with the log messages: ...

I think there is no "mature" Linux initiator software yet, open-iscsi is not stable yet. But what dow you think about it? Is a initiator bug really, can be a target problem? Do you use which initiator implementation on Linux clients? Thanks for your time! Leal.
