psykix Posted May 16, 2017 Share Posted May 16, 2017 Any idea why I am seeing the following regularly in my event log? Don't seem to have any adverse effects, all disks showing as healthy and scanned. This is reported on Drive 5 - which is the Drivepool with a volume label. Log Name: System Source: disk Date: 15/05/2017 16:17:21 Event ID: 153 Task Category: None Level: Warning Keywords: Classic User: N/A Computer: PLEXSERVER Description: The IO operation at logical block address 0x1 for Disk 5 (PDO name: \Device\0000002d) was retried.

0 psykix Posted May 16, 2017 Author Share Posted May 16, 2017 Never mind. I should have searched! I see that the above is expected behaviour due to being an emulated drive. Quote Link to comment Share on other sites More sharing options...
0 Christopher (Drashna) Posted May 18, 2017 Share Posted May 18, 2017 Not a problem. And specifically, the "logical block address" is well, "LBA" which is the "new" version of CHS (Cylinders, heads, sector) mapping. By "new", I mean that it's been in use for a long while now, and allows for much higher data density (as you can fit more sectors at the outside, but less on the inside, and this allows for it to be spliced up in that way). But since this is a query to a specific sector (block of data) on the pool, it will fail as there are no actual blocks of data on the pool. So yes, these are entirely normal.
