Hi,

 

I just noticed something weird... I'm watching an episode and noticed none of the disks are spun up. 

 

Looking in UnMenu at the "Open Files" section, it correctly shows:

COMMAND    PID USER  FD  TYPE DEVICE      SIZE NODE NAME

shfs      3497 root    4r  REG    9,3 1172583506  261 /mnt/disk3/TV/Episode/Season_x/FileNameHere.mkv

cache_dir  7728 root  cwd    DIR    9,1        192    2 /mnt/disk1

cache_dir  7730 root  cwd    DIR    9,2        192    2 /mnt/disk2

cache_dir  7732 root  cwd    DIR    9,3        160    2 /mnt/disk3

sleep    27700 root  cwd    DIR    9,3        160    2 /mnt/disk3

sleep    27704 root  cwd    DIR    9,1        192    2 /mnt/disk1

sleep    27706 root  cwd    DIR    9,2        192    2 /mnt/disk2

 

Any ideas what's going on here?  Is it getting cached somewhere?

Exactly.  Linux buffers as much as it can in memory.  Odds are high the file is one you wrote recently to the array and you've not read or written a lot of other files since to displace it from the disk buffer cache.

That's amazing... streamed the whole thing from memory!  Thanks for the info Joe!
