Hi
I think I hit the cifs bug described at http://wiki.centos.org/TipsAndTricks/WindowsShares and http://bugs.centos.org/view.php?id=1776
As CentOS Wiki said, CentOS 5.0 do have a bug fixed cifs.ko, so I thought it should be in CentOSPlus repository ... so I upgrade my kernel and using 2.6.18-8.1.10.el5.centos.plus. After I use this kernel release, I check the cifs.ko and see the following:
$ modinfo /lib/modules/2.6.18-8.1.10.el5.centos.plus/kernel/fs/cifs/cifs.ko filename: /lib/modules/2.6.18-8.1.10.el5.centos.plus/kernel/fs/cifs/cifs.ko version: 1.45 description: VFS to access servers complying with the SNIA CIFS Specification e.g. Samba and Windows license: GPL author: Steve French sfrench@us.ibm.com srcversion: 7C1A34565EA00CE993D56FA depends: vermagic: 2.6.18-8.1.10.el5.centos.plus SMP mod_unload 686 REGPARM 4KSTACKS gcc-4.1 parm: CIFSMaxBufSize:Network buffer size (not including header). Default: 16384 Range: 8192 to 130048 (int) parm: cifs_min_rcv:Network buffers in pool. Default: 4 Range: 1 to 64 (int) parm: cifs_min_small:Small network buffers in pool. Default: 30 Range: 2 to 256 (int) parm: cifs_max_pending:Simultaneous requests to server. Default: 50 Range: 2 to 256 (int)
The cifs.ko is version 1.45 .... I think this is still the buggy version, right ???
I have two CentOS 5.0 boxes, both running 2.6.18-8.1.10.el5.centos.plus and using automounter to mount WinXP's share. I use this as part of my daily backup ... and both boxes crash quite often ... specially when I have large files cross cifs mounted filesystem using rsync.
For small files, they are quite stable.
Could someone tell me ... did I use the bug fixed cifs.ko ? Or how can I fix this problem ? Thanks
