Hi, we currently have a raid-z1 pool resilvering (two damaged devices in different vdevs), but a third disk in one of the degraded vdevs occasionally timeouts:
Jul 7 06:25:36 imksunth8 scsi: [ID 243001 kern.warning] WARNING: /scsi_vhci (scsi_vhci0): Jul 7 06:25:36 imksunth8 /scsi_vhci/disk@g5000cca2441ed63c (sd184): Command Timeout on path mpt_sas4/disk@w5000cca2441ed63d,0
The problem: These hiccups cause the resilvering to RESTART ! Which doesn't help to get the job quickly done, and just accelerates the wear on the already unhealthy third disk, and will finally spiral down to complete dataloss because of 2-disk-failure on a z1 vdev. Is there a way to switchoff this behaviour via a kmdb parameter which can be set while operating (it's an older illumos-cf25223258 from 2016) ? -- Dr.Udo Grabowski Inst.of Meteorology & Climate Research IMK-ASF-SAT https://www.imk-asf.kit.edu/english/sat.php KIT - Karlsruhe Institute of Technology https://www.kit.edu Postfach 3640,76021 Karlsruhe,Germany T:(+49)721 608-26026 F:-926026
