Look for a single drive that has substantially greater await than ~10msec. If all the drives except one are taking 6-8msec, but one is ve...

[merging] The HBA the drives are attached to has no configuration that I?m aware of. We would have had to accidentally change 23 of them ?

...t fairly fast (20000K/sec - the limit that's been set), but then quickly drops down to about 4000K/Sec. dev.raid.speed sysctls are at the defaults: dev.raid.speed_limit_max = 200000 dev.raid.speed_limit_min = 1000 Here's 10 seconds of iostat output, which illustrates the issue: [root at r1k1log] # iostat 1 10 Linux 3.10.0-327.18.2.el7.x86_64 (r1k1) ? ?05/24/16 ? ?_x86_64_? ?(32 CPU) avg-cpu:? %user? ?%nice %system %iowait? %steal? ?%idle ? ? ? ? ? ?8.80? ? 0.06? ? 1.89? ?14.79? ? 0.00? ?74.46 Device:? ? ? ? ? ? tps? ? kB_read/s? ? kB_wrtn/s? ? kB_read? ? kB_wrtn sda? ? ? ? ? ? ? 52.5...

LSI/Avago?s web pages don?t have any downloads for the SAS2308, so I think I?m out of luck wrt MegaRAID. Bounced the node, confirmed MPT Firmware 15.10.09.00-IT. HP Driver is v 15.10.04.00. Both are the latest from HP. Unsure why, but the module itself reports version 20.100.00.00: [root at r1k1 sys] # cat module/mpt2sas/version 20.100.00.00 On 2016-05-25, 3:20 PM, "centos-bounces at centos.org on behalf of m.roth at 5-cent.us" <centos-bounces at centos.org on behalf of m.roth at 5-cent.us> wrote: >John R Pierce wrote: >> On 5/25/2016 11:44 AM, Kelly Lesperance...
