Description
While messing around in cache control settings I noticed that I can no longer permanently set readcache_max_filesize with any of the known methods. In all cases I get errors:
[root@mgs ~]# lctl conf_param obdfilter.lustre-OST0003.readcache_max_filesize=1M
error: conf_param: Cannot allocate memory
[root@mgs ~]# lctl conf_param lustre.obdfilter.readcache_max_filesize=1M
Make sure cfg_device is set first.
Per a tips and tricks discussion adilger gave at LUG2010 the recommended method was:
<fs>.<subsys>.readcache_max_filesize however this no longer appears to work.
Am I just doing this wrong or is this really a bug?
