kernel error logs

Hello

since 2007/09/21-14:03 i became two error messages from our DSS-Server.

Sep 21 17:31:38 dss kernel: fileio_make_request(62) I/O error 3584, -28
Sep 21 17:32:41 dss kernel: fileio_make_request(62) I/O error 4096, -28

Is this a kernel problem if someone want to write to the initiated iSCSI-Target on a w2k3-Server?
While this error messages appear the Target is only readable.

There are two iSCSI-Targets defined (1000GB and 250GB) on the DSS each initiated by one W3k3-Server with the MS iSCSI Initiator. By the same time, there is a NAS Volume which is integraded on the two W2k3-Server with 'Shared Folders' and on a Linux-Server with smbmount.

Has anyone an idee how to fix this?
Thanks for any help you can give

Kind regards,

What version of DSS are you running? Are you using MPIO?
Check the dmesg logs to see if watchdog message is associated with NIC or if you are using any bonding try with out bond (only if you are not using MPIO). If you do have watchdog associated with NICs check switch or cables.
Run check disk as well to from the W2K3 server.

hello

Thanks for your answer.
I've checked the version of the DSS-Module: 1.15.DB00000000.2553
There are four NIC's in this server, where three of them are bonded while the fourth is standalone for mantanance.
As far as i can see, the MS iSCSI Initiator is configured to use MPIO

I will check dmesg, cable, switch and will post the result as soon as possible. I also will do an check disk on the W2k3-Servers

thanks

kind regards

If possible try to update with version 1.23 (we saw many errors with this version of 1.15) or 1.30 (if 1.30 please read the release notes - very important info on removing Logical Volumes).
