Optimumcache - not doing much?

[kennethmaze]

I have a server which has only WordPress sites on it. Around 400 of them. So I thought that Optimumcache would be caching many files.
I installed it a few days ago. These are the results:

df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 1.8T 1.3T 449G 75% /
tmpfs 16G 8.0K 16G 1% /dev/shm
/dev/md0 221G 28G 182G 14% /var
/usr/tmpDSK 4.0G 256M 3.5G 7% /tmp
/var/share/optimumcache/DiskDescriptor.xml

                       24G   16G  7.1G  69% /var/cache/optimumcache

# optimumcache stat

csums:        3279 (0.1%)

fetched   uncached     cached percentage  de-duplication coefficient

inodes:    2565371    2562092       3279       0.1%                        0.1%

size,kB: 180697235  180653167      44067       0.0%                        0.0%

RAM,kB:   13927220   13895908      31312       0.2%                        0.2%

Surely these figures should be higher? Or is this to be expected?

This numbers tells that there are very few files having csums (0.1%) in Linux FS cache -

> # optimumcache stat
> csums: 3279 (0.1%)
> fetched
> inodes: 2565371
> ...

List files in Linux FS cache having no csums -

# optimumcache dump --all --resolve-filenames | grep -w f:cp | sort -k7

If you see that wordpress files are there, then wordpress files marking step most probably was failed.

It might happen that mark process has not finished correctly. Could you please list -

# grep optimumcache mark /var/log/messages*

and

# cat /var/share/optimumcache_store

Thanks.

Hello Bogdan

# grep optimumcache mark /var/log/messages*

no result

# cat /var/share/optimumcache_store

optimumcache mark --recursive /home
optimumcache mark --recursive /home
optimumcache unmark --recursive /home

It appears you unmark everything with the last command. You have to mark again with:

optimumcache mark --recursive /home
