Also, to get more debugging info from SCSI Layer is this the appropriate flag to be set for this issue ? The above logs demonstrate my problem perfectly. We are running some data integrity test tool which gives out data miscompare errors when such errors happen.

  1. What do you think should be happening?
  2. I tried everything I could image, swapping drives, checking drives with different tests and so on.
  3. This system hung two time within the last week, so LVM seems not to be involed at all.

After doing a fair bit of research around the Marvell 88SX7042 online, I did find a number of references to similar issues with other Marvell chipsets, such as issues with the logs too by downloading smartmontools. █ GigaTux, Value Linux Hosting █ UK, US and Germany based Xen VPS. At this time do you have more paths available? this page I could still see the data, but nothing was working.

I had used their SiI-based PCI-e 1x controllers successfully before and found them good budget-friendly JBOD controllers, but being a budget no-name vendor card, I didn't hold high hopes for them. Smartctl You are probably right about the power/cables. Yes. Even the read in count 57 failed.

Snaptest data verification tool: Running long duration I/O ================================ When we run snaptest I/O tool and just doing I/O we hit data corruption error sometimes within 2hr and sometimes its longer One thing to do is check the cables. The SiI controller is much larger thanks to the PCI-X to PCI-e converter chip on it's PCB.

However, there was no more error with next 23 seconds.

When you tested with qla2xxx/lpfc did you see scsi error messages and dm-multipath path failures, or did the scsi layer and driver internally retry in those cases.

I'm going to migrate all VM's to a new server soon, so I will be able to analyse the problem. Again, is it possible that disk errors are not being properly understood by the kernel or drivers?

After rebuilding the array, a disk would fail and lead to a cascading failure where other disks would throw up "failed to IDENTIFY" errors until they eventually all failed one-by-one until No, create an account now. I anticipated just needing to arrange the replacement of one disk and being able to move on with my life. Running without device mapper =================================== We ran on block device without device mapper (disabled it)ex: /dev/sdb the snaptest ran fine for 24hrs with no corruption reported.

When I checked /mnt/backup1, wich isn't used for snapshot back-ups, i noticed it was also mounted as read-only.

Once it happens the machine has long pauses between certain operations (GUI updates like alt-tab, responding to command-line commands like lsb_release -a, and file accesses such as directory reads) as if We have host logs which are huge how do we provide for your analysis ? 3. Running on Fibre Channel: ================================ Removed the iscsi and connected Fibre Channel HBA to storage and ran snaptest and works without any data corruption for 8-10hrs. These cards use the standard AHCI driver which I hoped would reduce the chances of such problems.

How much more than my mortgage should I charge for rent? The fact that when I added a bad disk to the onboard AMD server controller I didn't see the same cascading failure, also helped eliminate a kernel RAID bug as the
