Two main issues, first is as the subject says - deleting large files is VERY slow. I have the following drive setup and am using a Windows 10 PC. All updates and firmware up to date. Drobo and PC are connected to a gigabit switch, PC is gigabit.
2 x 4 TB
3 x 3 TB
So a total of 12TB and then 9 or so after RAID. I have about 8 TB of that in use, maybe a bit more (less than 10% free in case that matters). A large chunk of this is movies that range from 1GB - 15GB. Deleting a single large file, in this range, is extreeeeeeeemely slow. I’ve tried from Windows explorer with just delete and with shift delete, no difference. It estimates forever, shift or not. I’ve tried a single file at a command line, just “del file.txt” and “del /q /f file.txt” Also to toss in if I delete a directory with say 5-20 small files and folders that deletes very quickly, just as I’d expect, no issues at all. Moving large/huge files (to another folder on the Drobo) is basically instantaneous. I’ve seen some suggestions about using Cygwin but don’t currently have that installed.
The secondary problem is when this happens it almost freezes the drobo, it doesn’t stop responding to ping but if I’m watching one of the movies it always freezes or otherwise crashes. Say 30 seconds later when the file is finally deleted (say a 10GB file) everything goes back to normal.
Thoughts? I can’t imagine what I’m doing wrong as this is really simple stuff.
