[Lustre-discuss] WARNING: data corruption issue found in 1.8.x releases

[Lundgren, Andrew]

Does this need to be run on EACH OSS?  Is there a central way to do it on the MDS?

You recommend disabling the read and the write as the settings indicate or just the read as the text indicates?

-----Original Message-----

A patch is under testing and will be included in 1.8.1.1.
Until 1.8.1.1 is available, we recommend to disable the OSS read cache
feature. This feature can be disabled by running the two following
commands on the OSSs:
# lctl set_param obdfilter.*.writethrough_cache_enable=0
# lctl set_param obdfilter.*.read_cache_enable=0

This has to be done each time an OST is restarted.

Best regards,
Johann, for the Lustre team
