Hi All
New to forum so first post :) Used FreeBSD before but first time using FreeNAS.
I just started using FreeNAS 11 for my iSCSI shared storage for my vSphere 6.5 cluster. I have the following volumes configured in FreeNAS:
RAID 10 comprised of 4 Samsung SM863 480GB SSDs
RAID 1 comprised of 2 Samsung Pro 850 512GB SSDs
Single Western Digital 4TB SATA drive
Since I want to use VAAI with vSphere I created all the above as a zvol and ticked the sparse volume option.
It seems to be working well except I get these warning messages in the vmkernel.log on each of the ESXi hosts:
2017-11-08T21:56:44.833Z cpu15:66376)WARNING: ScsiDeviceIO: 2728: Space utilization on thin-provisioned device naa.6589cfc0000006f22a5c1eb41598028b exceeded configured threshold
This error seems to occur every 15min.
I also get these every 5min:
2017-11-08T21:56:44.833Z cpu15:66376)NMP: nmp_ThrottleLogForDevice:3617: Cmd 0x2a (0x439501012ec0, 129131) to dev "naa.6589cfc0000006f22a5c1eb41598028b" on path "vmhba64:C0:T1:L0" Failed: H:0x0 D:0x2 P:0x0 Valid sense data: 0x6 0x38 0x7. Act:NONE
If I run
I have tried changing the "Pool Available threshold" in the global configuration and/or changing it on each extent to a really low or high value or well as setting it to 50% or zero but I still keep getting these warnings despite having lots of free disk space in each volume in FreeNAS.
What am I missing here or doing wrong and how can I stop so many warnings being logged all the time?
Thanks for any help! :)
