I have a Nexenta ZFS system serving a large NFS volume (using ~85% of 250 TB). One of the 70 disks failed over a week ago, and the system is resilvering a hot spare without issues (other than the large performance losses due to the intense resilvering I/O).
I know that having more free space will reduce the time needed for future resilverings, so I'm planning to clean up ~70 TB from the NFS volume soon.
But, I'm not sure if doing the cleanup during the current resilver will cause problems, or if it'd reduce the time needed for the current resilver, which brings up my question:
- will deleting files negatively impact an ongoing ZFS resilver?
