CIFS freezes, SMART errors the culprit?
I was gonna post about having freezes when copying files around using CIFS, but then I checked the SMART data of the drives and I think there's been some changes since last time I did that. I don't kn...
I'd update my backups and shift files to the new Pro before I replaced any disks on this one. With two suspect disks you'd be putting the volume at risk when you replace/resync.
Also, 90% full could explain a lot of performance problems. Hopefully your new Pro will have bigger drives.
Once you've taken care of the backup, I'd replace disk 4, but just watch disk 3 for now. The format for read error rate is vendor specific, so it is hard to understand the significance of the raw number. The load cycle count is unexplained, but still it is well below the drive specs. But current pending sector count is the "read" equivalent of a reallocated sector - the read attempt failed. If a write on the same sector had failed it would have been reallocated. (on a read, you don't know what the data is, so there is no point in reallocating). Offline uncorrectable counts are just as bad.
