Unable to create remote FLR. The target does not have enough reserved scratch free space ...

ISSUE

Upon attempting to create a remote FLR for a hot backup copy, you encounter the error "The target does not have enough scratch free space (* KB) for the request (* KB).". The error persists even after verifying that no other remote FLRs running are running.

RESOLUTION

The remote FLR allocation configured on the target may need to be increased to support larger hot backup copy backup sizes. 

There are two options in this particular scenario.

  • Increase the amount of backup storage allocated to the target which increases the available allocation for remote FLR. 
  • Increase MaxFLRDownloadSizePCT (default 25) by a sufficient amount (not to exceed 80) to allow for the recovery of the affected backup via remote FLR.  
1. SSH to target appliance
2. Determine the current value for the MaxFLRDownloadSizePCT parameter:
[[email protected] ~]# bputil -g SelfService MaxFLRDownloadSizePCT NA /usr/bp/bpinit/master.ini
25
3. Use the bputil command to update the master.ini or manually modify it via UI or VIM (cli text editor):
[[email protected] ~]# bputil -p SelfService MaxFLRDownloadSizePCT 50 /usr/bp/bpinit/master.ini
4. Verify that the parameter value has been updated:
[[email protected] ~]# bputil -g SelfService MaxFLRDownloadSizePCT NA /usr/bp/bpinit/master.ini
50
 

CAUSE

The remote FLR storage required for the selected backup exceeds the percentage of free space available on the target as defined by the [SelfService] MaxFLRDownloadSizePCT parameter in the master.ini.
