  • Events in EMS:

wafl.vol.fsp.full: volume
vol1__0004@vserver:XXXXXXXXXX insufficient space in FSP wafl_remote_reserve to satisfy request of 2 holes and 2 overwrites.

wafl.vol.full: Insufficient space on volume vol1__0004@vserver:XXXXXXXXX to perform operation. 28.0KB was requested but only 1.00KB was available.

[wafl.vol.full:alert]: Insufficient space on aggregate aggr_1 to perform operation. 4.00KB was requested but only 1.00KB was available.

  • Insufficient space in the aggregate may lead to rebalance failure as there is not enough space to store the required metadata:

[Node-01: OnDemand_Handler2: wafl.ondemand.exception:debug]: params: {'exception_info': 'Cannot quiesce source file. No space is left on volume {DSID:xxxx}. File move job c2bbcfb6-2d8d-4c63-xxxxxxxxxx.'}
[Node-01: OnDemand_Handler3: wafl.ondemand.done:notice]: Cannot complete file move. Operation destroyed. Cannot quiesce source file. No space is left on volume {DSID:xxxx}. FlexGroup rebalance operation on volume vol01 (DSID xxxx to yyyy). path=/file_path destination_constituent=vol01__0003 operation_UUID=c2bbcfb6-2d8d-xxxxxxxxxxxxxxxxxxx.
