[Gluster-users] Possible error not being returned

[Ankireddypalle Reddy]

Hi,
       A disperse volume  was configured on  servers with limited network bandwidth. Some of the read operations failed with error

[2016-05-16 18:38:36.035559] E [MSGID: 122034] [ec-common.c:461:ec_child_select] 0-SDSStoragePool-disperse-2: Insufficient available childs for this request (have 1, need 2)
[2016-05-16 18:38:36.035713] W [fuse-bridge.c:2213:fuse_readv_cbk] 0-glusterfs-fuse: 155121179: READ => -1 (Input/output error)

For some read operations just the following error was logged but the I/O did not fail.
[2016-05-16 18:42:45.401570] E [MSGID: 122034] [ec-common.c:461:ec_child_select] 0-SDSStoragePool-disperse-3: Insufficient available childs for this request (have 1, need 2)
[2016-05-16 18:42:45.402054] W [MSGID: 122053] [ec-common.c:116:ec_check_status] 0-SDSStoragePool-disperse-3: Operation failed on some subvolumes (up=7, mask=6, remaining=0, good=6, bad=1)

We are receiving corrupted data in the read operation when the error is logged but the read call did not return any error.

Thanks and Regards,
Ram
