Hi !
In the last few days we've observed an increasing number of Nodes,
which are no longer be reached and have to be rebooted
In the /var/log/messages we see a lot of lines with e.g.
Oct 22 18:48:26 bird858 kernel: afs: disk cache read error in CacheItems slot
25254 off 2020340/13880020 code -5/80
Oct 22 18:48:26 bird858 kernel: afs: disk cache read error in CacheItems slot
25253 off 2020260/13880020 code -5/80

Oct 22 18:48:26 bird858 kernel: afs: disk cache read error in CacheItems slot
25251 off 2020100/13880020 code -5/80
till nothing happens anymore ...
The clients are Centos 7.5 , 3.10.0-862.14.4.el7.x86_64, OpenAFS 1.6.23 built
2018-09-12 ([email protected])
Any hints for the possible reason ?
Thanks & Cheers,
Martin
