partial resilvering

[gearhead]

I ran zpool status I notice 384K was resilvered. I am guessing that Freenas found a few bad blocks on one drive and flagged it . Am I correct in my assumption? if so how can I check which drive has bad blocks?

Code:

root@freenas11:~ # zpool status
  pool: Files
 state: ONLINE
  scan: resilvered 384K in 0 days 00:00:01 with 0 errors on Tue Jul  3 15:38:28 2018
config:

		NAME											STATE	 READ WRITE CKSUM
		Files										   ONLINE	   0	 0	 0
		  mirror-0									  ONLINE	   0	 0	 0
			gptid/274a0466-c7e7-11e7-ae38-d43d7e18b257  ONLINE	   0	 0	 0
			gptid/27f23ea0-c7e7-11e7-ae38-d43d7e18b257  ONLINE	   0	 0	 0

errors: No known data errors

If a drive dropped off and then reconnected, you can get a small resilver like that. Check logs or SMART, or consider any potential cable problems.

Thanks for your response. Which log should I check (there are so many of them)?
