Error message

ERROR - "Failed to write /data/521/534297.bhd allow_write F skip_write_fail F"

Diagnosis

One possible cause is that cache eviction cannot clean up any data from the local cache directory for non-MSDP system file writes.

The cache eviction is triggered when the high watermark setting (HighWatermark) for the directory is reached. Once the high watermark is reached, data is purged when the used space reaches the midpoint between HighWatermark and LowWatermark (high+low)/2 and continues until LowWatermark is reached. If the rate of incoming data exceeds the rate where the watermark can be maintained, the jobs begin to fail.

Since the upload speed to the cloud is slower than the hard disk drive write speed, this situation can arise when the partition for the local cache directory is small. Increase the space that is allowed for the local cache directory.
