[Lustre-discuss] Need Help

[Colin Faber]

Hi,

Additional logging from the MDS and OSS's is required to really tell 
whats going on, that said you can try and verify that your OSS nodes can 
successfully contact your MDS and MGS nodes, lctl ping will indicate 
this. After that if you find they are successfully contacting each other 
you can try and abort recovery both on the MDT and OST's you're 
attempting to mount. (-o abort_recov mount option).
