    • Not on Frontera because of non PSM2 fabric
  • DAOS-5895 - IOR EC object type DAOS_OC_EC_K16P2_L256K IOR with FPP is crashing the server
    • Did not observed any crash on Frontera
  • DAOS-5777 - EC IOR test is failing for file-per-process which has higher Chunk size
    • Did not tried on Frontera but will likely go away ?
  • New Defect on Frontera (18 servers/80 client [1600 tasks]) where read is getting stuck (But no server crash or client crash). Need to try few more things to get more debug info
    • object ERR src/object/cli_shard.c:552 dc_rw_cb() RPC 1 failed: -1032
