[HPDD-discuss] ost-survey hangs on client 2.4

Hi, I was trying to run ost-survey on this environment mds, oss: lustre 2.4.2 (CentOS 6.5 with lustre patched kernel RPM) client: lustre 2.4.2 (CentOS 6.5 patchless client, lustre iokit 1.4.0.1) command line: ost-survey -s 100 /lustre but the script hangs each time, chewing all the CPU in the attempt to echo 0 in /proc/fs/lustre/llite/*/max_cached_mb . This is due to the subroutine cache_off in the ost-survey script. But while in a lustre client 2.1.6 the max_cached_mb appears to me as a single number # cat /proc/fs/lustre/llite/*/max_cached_mb 18114 on a 2.4.2 client is different # cat /proc/fs/lustre/llite/*/max_cached_mb users: 2 max_cached_mb: 96766 used_mb: 21806 unused_mb: 74960 reclaim_count: 0 Am I missing a new version of ost-survey or should I simply get rid of those dangerous lines in the script? Thanks, Francesco
