[lustre-discuss] OSS node crash/high CPU latency when deleting 100's of empty test files

[Sid Young]

Thx Karsten, looks like I found it at the same time you posted... I
will have a go at re-imaging with 1160.6.1 (the build updates to
1160.15.2) and re-testing.

Do you know if 2.14 will be released for Centos 7.9?

Hi Sid,

if you are using a CentOS 7.9 kernel newer than
3.10.0-1160.6.1.el7.x86_64 then check out LU-14341 as these kernel
versions cause a timer related regression:
https://jira.whamcloud.com/browse/LU-14341

We learnt this the hard way during the last couple of days and
downgraded to kernel-3.10.0-1160.2.1.el7.x86_64 (which is the
officially supported kernel version of lustre 2.12.6). We use ZFS.
YMMV.
