Hi, We’re running into an error with a particular directory. It is weird because it can be resolved in an unexpected way, but only for a time. The error manifests as:
el3:out> lfs getstripe -M /projects/naris/pcm_110819/NARIS_TechBreak2050_missingDPV/StageC_RT5min error opening /projects/naris/pcm_110819/NARIS_TechBreak2050_missingDPV/StageC_RT5min: Permission denied (13) llapi_semantic_traverse: Failed to open '/projects/naris/pcm_110819/NARIS_TechBreak2050_missingDPV/StageC_RT5min': Permission denied (13) error: getstripe failed for /projects/naris/pcm_110819/NARIS_TechBreak2050_missingDPV/StageC_RT5min. The temporary resolution is: el3:out> ls /projects/naris/pcm_110819/NARIS_TechBreak2050_missingDPV/StageC_RT5min ~Model ( c_RT5min_TechBreak2050_092P_OLd000_001 ) Log.txt Model c_RT5min_TechBreak2050_092P_OLd000_033 Solution.h5 Model c_RT5min_TechBreak2050_092P_OLd000_062 Solution.h5 … Then el3:out> lfs getstripe -M /projects/naris/pcm_110819/NARIS_TechBreak2050_missingDPV/StageC_RT5min 1 el3:out> However, the getstripe command will only continue to work for about 10 minutes, then it goes back to the permission denied errors. It only happens with a selection of files or directories, so we were thinking it might be connected to a particular OSS or MDT, but not sure what to look for. I am not the Lustre admin, so please forgive incomplete information. If folks can request specific command output, preferably from user space, that would accelerate my ability to answer questions. If something needs to get run while logged into a particular Lustre component (MDT, OSS, etc.), please do not hesitate to assume that I don’t know that. We’re running Lustre 2.10.7 provided by DDN on CentOS 7.4. All help appreciated, thanks! Chris -- Christopher H.
