Greyhole constant disk activity, is this normal?

Hi all

I setup my Amahi server about 19 days ago, I have been very impressed with it so far.

I have noticed that Greyhole is constantly working with files on the disks for over 2 weeks now. I haven't written any major number of files to the shares since it was first setup, but for over 2 weeks the disk activity is flat out. Greyhole appears to be doing it's job and the queue numbers do change but sort of hover around similar numbers so it's moving things around, but is it normal for it to be hammering the disks for such a long time (around 2 weeks now?). I worry that the lifespan of the drives may decrease if they are being written to all day every day over a long period of time that's all.

Here is the info provided on your guide:

[root@localhost ~]# uname -r; rpm -q samba hda-greyhole 2.6.35.14-106.fc14.x86_64 samba-3.5.11-79.fc14.x86_64 hda-greyhole-0.9.2-1.x86_64
FPaste didn't seem to work correctly and didn't give me an ID to view the paste so here's smb.conf:

Hopefully that's all you need :)

Does your owncloud have a lot of activity?

Are the backup or transfer shares getting a lot of data from clients? ... lots of activity?

I ran into similar system resource-eating scenarios with the F14 install with greyhole.
If there's an endless supply of changes to be made, and especially with small files, then greyhole and samba work frantically to apply the changes.

Every time something changes in a greyhole pooled share, something more needs to be done for indexing. If you have those heavy-access folders outside the pool, you're prone to much less thrashing.

It seems that you have 1 drive in the pool; please ensure none of your shares are asking for more than a single copy to be kept.

Also we would appreciate if you attached a text file rather than posting hundred's of lines of text. Makes it hard to read in my opinion.

Thanks :)
