NDMP backup hangs

[spulipat]

HARDWARE LINUX_RH_X86
VERSION NetBackup 7.5.0.5
 

NDMP backup hangs until NDMP timeout vaule and fails with 99. Backup hangs for only one volume (tried backup at qtree level) and runs fine for other volumes from the same filer. NetApp admin performed health check on the volume and found no issues with this volume. Volume is 70% occupied.

Use NDMP_PROGRESS_TIMEOUT:

Thank you watsons. But NDMP PROGRESS TIMEOUT is already set to 24 hours, that is why backup hangs (doing nothing) for 24 hours and fails with 99.

Will try increasing it to 7 days for now. (hope this doesn't affect existing backups).

Any alternative to narrow down this issue is helpful.

Hi,

Can you run this command on Netapp Filer 

options ip.fastpath.enable off 

Then try to take NDMP Backup and see how it works
