We just setup a lustre system, and all looks good, but there is this nagging error thats floating about. When I reboot any of the nodes, be it a OSS or MDS, I will get this:
[r...@meta1 ~]# dmesg | grep sdc sdc : very big device. try to use READ CAPACITY(16). SCSI device sdc: 4878622720 512-byte hdwr sectors (2497855 MB) sdc: Write Protect is off sdc: Mode Sense: 77 00 10 08 SCSI device sdc: drive cache: write back w/ FUA sdc : very big device. try to use READ CAPACITY(16). SCSI device sdc: 4878622720 512-byte hdwr sectors (2497855 MB) sdc: Write Protect is off sdc: Mode Sense: 77 00 10 08 SCSI device sdc: drive cache: write back w/ FUA sdc:end_request: I/O error, dev sdc, sector 0 Buffer I/O error on device sdc, logical block 0 end_request: I/O error, dev sdc, sector 0 This doesn't seem to affect anything. fdisk -l doesn't even report the device. The same(thought of course different block device sdd, sde, on the OSSs), happens on all the nodes. If I run pvdisplay or lvdisplay, I'll get this: /dev/sdc: read failed after 0 of 4096 at 0: Input/output error Any ideas? David -- Personally, I liked the university. They gave us money and facilities, we didn't have to produce anything! You've never been out of college! You don't know what it's like out there! I've worked in the private sector. They expect results. -Ray Ghostbusters _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss
