[HPDD-discuss] Inactive OST

Hello, I have recently added 2 more OSS nodes and assigned 1 OST to each node, but client report these new OSTs are inactive, my other OSTs on older OSS servers looks fine and they are active. I do not find any reason in the logs of MDS/OSS/Client. I tried following things but none of them seems to work, this is a test setup: 1. Unmount and Mount the lustre file system on the client 2. Unmount, reformt the MDT and OSTs followed by mounting MDT, OST and client 3. Run command to activate OST manually - "lctl --device lustre-OST0000 activate", but I get following error: a. error: activate: failed: Inappropriate ioctl for device Please advise, my setup is: * 1 MDS / MGS Server * 4 OSS Servers o 2 OSS servers running on 2 different hypervisors o 6 OST devices, 4 are configured with 1st two OSS Servers and one each on new OSS Servers * 8 Clients o 4 client each on 2 hypervisors * All data devices are on an external storage array o LUNs for 1st two OSS are coming from one array port o LUNs for 3rd and 4th OSS are coming from different array port Thanks, -Upanshu Upanshu Singhal EMC Data Storage Systems, Bangalore, India.
