Rebalance fails to migrate files on EC volumes: [2017-05-03 07:37:35.643291] E [MSGID: 109023] [dht-rebalance.c:740:__dht_rebalance_create_dst_file] 0-ecv-dht: fallocate failed for /dir1/linux-4.10.4/include/linux/smpboot.h on ecv-disperse-1 (Operation not supported) [2017-05-03 07:37:35.643320] E [MSGID: 0] [dht-rebalance.c:1516:dht_migrate_file] 0-ecv-dht: Create dst failed on - ecv-disperse-1 for file - /dir1/linux-4.10.4/include/linux/smpboot.h RCA: The rebalance code was recently changed to use fallocate when creating the dst file. However it looks like this is not supported on EC volumes: 736 int32_t ec_gf_fallocate(call_frame_t * frame, xlator_t * this, fd_t * fd, 737 int32_t keep_size, off_t offset, size_t len, 738 dict_t * xdata) 739 { 740 default_fallocate_failure_cbk(frame, ENOTSUP); 741 742 return 0; 743 } With this change, rebalance will fail on EC volumes.
