strange system info ** solved **

[giantmr4]

after upgrading from v2.1d to v2.2c, i find strange on the \"system info\" webpage

Storage
Swap: 1841497MB of 952335MB used (193%)
System: 1019600MB of 1825693MB used (55%)
Data: 193MB of 3180MB used (6%)

My meteohub only has 4G at most. How can the swap and system size can be larger than 4G?

1.8 TB for system data looks a bit too much for me as well :woohoo:

I cannot remember having changed something in that area of the application when going from version 2.1d to 2.2c. Is the problem persistent or does it skip to normal operation in the meantime?

[giantmr4]

It is now using 2.2d.
The figures are still not correct after reboot some times.

However, I find this does not affect any operations of the meteohub (include data logging and graph generation)

I guess there is some place that stores these figures, however it is not updated correctly after the upgrade. ;)

hmm... as Meteohub digs out the underlying data from the depth of the system and i have never seen that strange numbers, I would like to understand what is going on. Any chance for me to login to your system?

I know some linux commands. For your information ...

However, when compared to \"system info\" webpage, the figures are different. :dry:

ok, what does \"swapon -s\" report to you?

[giantmr4]

\"swapon -s\" is same as \"cat /proc/swaps\".

root@meteohub:~$ swapon -s
Filename Type Size Used Priority
/dev/sda2 partition 131064 180 -1

[admin]

As the \"swapon -s\" data is used to display swap-size on Meteohub's \"system information\" page, it is hard to believe that it displays
\"Swap: 1841497MB of 952335MB used (193%)\"

Please check if display of swap size is still wrong. The swapon data looks fine and could hardly produce that... but as i have learnt, everything is possible :-)

[giantmr4]

It is normal after it is upgraded to 2.3 :)

reason was a buffer overrun that is fixed with the new versions.
