[Jfs-discussion] Finding while file a block belongs to

[Chris Penney]

We had a little san issue (dmesg below) and I got some messages about some write failures.  It's unclear to me how bad this is.  The system didn't really seem impacted other than the block write failures.  No jfs messages at all.  I am, perhaps mistakenly, assuming that this was in data blocks and not in metadata blocks (otherwise I assume it owuld have paniced as I mount with errors=panic).  Assuming that's true, is there anyway I can determine which file(s) were affected?

 

dm-5 is an lvm volume that contains dm-0 though dm-4.  Each of dm-0 though dm-4 is a 1TB lun with two paths (eg. 8:16 and 8:96).

 

Thanks,
