System Check
/!\ There are some issues with your system. Piwik will run, but you might experience some minor problems. See below for more information.

Your server is using an NFS filesystem.
This means Piwik will be extremely slow when using file based sessions.

I’ve just installed this on a new server running CentOS, my previous server which did not throw this error was Ubuntu however the filesystems where the same.

Previous server:

# df -T Filesystem Type 1K-blocks Used Available Use% Mounted on /dev/md3 ext4 957175772 91311940 817242044 11% / udev devtmpfs 11826784 12 11826772 1% /dev tmpfs tmpfs 4739428 424 4739004 1% /run none tmpfs 5120 4 5116 1% /run/lock none tmpfs 11848560 0 11848560 0% /run/shm /dev/md0 ext4 186491 78762 98101 45% /boot /dev/md2 ext4 1967504 41484 1826072 3% /tmp

Current server (with NFS Filesystem Error):

# df -T Filesystem Type 1K-blocks Used Available Use% Mounted on /dev/mapper/vg_beast-LogVol00 ext4 1152844716 19461548 1074822044 2% / /dev/cciss/c0d0p1 ext4 495844 67291 402953 15% /boot /usr/tmpDSK ext3 4128448 140232 3778504 4% /tmp tmpfs tmpfs 32985848 0 32985848 0% /dev/shm

Any thoughts on what I’m missing or doing incorrectly here?

Hey Matt,

Thanks for your reply and the assistance in my other thread. I previously followed the steps as advised and am still receiving the same error.

Previously:

# grep session_ config.ini.php session_save_handler = "dbtable"

Currently:

# grep session_ config.ini.php ;session_save_handler = "dbtable" session_save_handler = dbtable

Even with this configuration, I am still receiving the following notification in the System Check:

Your server is using an NFS filesystem. This means Piwik will be extremely slow when using file based sessions. piwik_ntfs.png 703×64 6 KB

Any other thoughts/suggestions?

It’s not an error - just a warning. Since you configured db-based sessions everything will be fine. If you read the message carefully it reads: “[…] will be slow WHEN using file based sessions”[/quote]

Hey Fabian,

Thank you for taking to time to reply and your insight. I know it may seem irrelevant, however if I’ve configured Piwik to use db-based sessions, shouldn’t it remove the warning, or advise further that I’ve added a configuration that should ‘correct’ the warned issue.

On another note, what could I have done to prevent the issue from the being? What ‘NFS Filesystem’ am I using, and which ones are supported that I should have chosen/setup instead?

Thanks again for your time.

I agree and the warning should not be shown if db-based sessions are activated. Please fix it.

And by the way. Since when is EXT4 a NFS-Filesystem?
I think your FS-Check is buggy.
Since the upgrade to version 2.14.2 the PHP-function shell_exec is needed.
After activating the function the warning for the NFS-Filesystem is shown.

And now your forum thinks that I am a bot. Best morning ever…sorry for that.

Hi there,

I agree and the warning should not be shown if db-based sessions are activated. Please fix it.

I think it would work. can you create an issue on our tracker? https://github.com/piwik/piwik/issues

Our check is: https://github.com/piwik/piwik/blob/2.14.2/core/Filesystem.php#L115-L119

can you paste the output of this command for you?

Thanks for the report. The check should be fixed with this patch in this issue System check diagnostic for "Filesystem" may detect wrong filesystem used · Issue #8525 · matomo-org/piwik · GitHub

let me know if after applying the patch you still have the problem
