Greetings;
I am getting very frequent disk errors and I can't figure out which
drive they are occurring on. I get two messages:
[174384.704895] sata_sil 0000:05:00.0: Event logged [IO_PAGE_FAULT
domain=0x0000 address=0x00000000cf99c100 flags=0x0000]
[174384.705153] AMD-Vi: Event logged [IO_PAGE_FAULT device=05:00.0
domain=0x0000 address=0x00000000df853000 flags=0x0000]
Several of each of them occur at once, every few seconds.
Is there any way that I can figure out which drive is causing the
problem?
1. Run diagnostics on each drive (say, the SMART long diagnostic) - that
should get you the disk id
2. Run the diagnostics again, on just your failing drive, look for the
drive with the flashing light
3. Depending on how old the drive is, your problem is probably a failing
drive
Having said that, you might want to track down what those log entries
actually mean. Traditionally, a "page fault" indicates that a page is
not found in memory, so the o/s is swapping the required page in from
disk. This might simply mean that you need more memory. You might look
at diagnostics that indicate memory usage and swapping.
