           Summary: Strange file locking problems
           Product: IO/Storage
           Version: 2.5
     KernelVersion: 2.6.22.6
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: SCSI
        AssignedTo: io_scsi at kernel-bugs.osdl.org
        ReportedBy: tuharsky at misbb.sk


Most recent kernel where this bug did not occur: 2.6.21.7
Distribution: Debian Etch
Hardware Environment: Opteron, Adaptec 2130S RAID controller
Software Environment: SAMBA
Problem Description: This is very similar to bug 8978, however this happens
even with RAID in status Optimal. The problem happens so far only with 2.6.22.6
kernel, not with 2.6.21.7, whereas the bug 8978 happens with both kernels.

We run fileserver on the machine. Twice a day the backup script archives all
documents locally on the server using tar.gz

Under moderate load (cca 2.2) the shared documents stop working for Windows
clients. They cannot open them, save them etc. It seems it is connected to the
tar accessing those documents. Only restart restored the normal operation.
