NASLite Network Attached Storage

Tony, Ralph,

I use NASLite-2 as the primary storage for all of my SageTV recordings. While debugging a problem (unrelated to NL2) Sage support told me that my NAS was taking a very long time to delete recordings. (Between 3 and 10 seconds depending on the size of the recordings which range from 1.5 GB to 12 GB.)

I do notice it takes a long time to delete recordings but I've always assumed it was something SageTV was doing.

Is it normal for NL2 to take so long to delete a large file? Is there anything that can be done to make the operation go quicker?

Thanks,

Tom

I'm waiting on naslite hdd version so I don't know too much about the product yet, but if you can use xfs file system in naslite you may want to try that. XFS is able to delele large files very quickly.

This is most probably due to the EXT3 journaling. From what I know, it is slower to delete files in general compared to say EXT2.

I have the same experience when deleting large files from my NASlite server. The larger the file, the longer it takes.

ALucas is correct. Ext2 will in theory be faster, but the filesystem will loose the benefit of a journal. Ext3 on the other hand does carry an overhead introduced by the filesystem journal. The time it takes to complete the task is also very relative to the hardware used. Amount of RAM, bus speed, drive types, physical file location and number of associated segments, etc., all influence the actual time it takes to delete a file and update the journal. With smaller files, much of the task is performed in cache but with larger files that can't be the case.

Hope that helps...

Thanks for the replies and explanations. This is not a show stopper for me, just an annoyance. In the long run I'll put up with the slow deletes for the EXT3 benefits.

PS. I've been running 2.05 and it is rock solid.
