splite Posted November 20, 2018 Share Posted November 20, 2018 I'm experimenting the same issue with a lot of devices, the 50Mo get filled up very quickly. Most of the time, nginx logs are responsible of that, but also hostapd in some case the wifi dongle is not present. This is very very annoying as the server can not work properly after the log folder is full. The only way is to move/remove files. I removed log2ram, but as I understand zram does the same !!

martinayotte Posted November 20, 2018 Share Posted November 20, 2018 Another possible workaround is to have a "crontab" job that delete or truncate files regularly ... Link to comment Share on other sites More sharing options...
Set3 Posted March 10, 2019 Share Posted March 10, 2019 Hi martinayotte On 11/20/2018 at 9:01 PM, martinayotte said: Another possible workaround is to have a "crontab" job that delete or truncate files regularly ... On var/log and var/log/.hdd : Done that, every hour, it works, obviously :-) . also using sed to remove the "IR event FIFO is full" lines But now, for a while or perhaps since then, my warning system, based on what df under /var/log reports gives false warnings : df misreports the real size eg : in WinSCP, the calculate button says 2.2MB, where df says 75% of 50MB Perhaps the varlog scripts are not happy with the delete/modify ? Reboot repairs the mismatch Edit : Moved to using du iso df, du is reporting correctly. so that is solved, but perhaps a point of attention for the developers ?

vfrolov Posted October 4, 2019 Share Posted October 4, 2019 Hello! How could it be? zram is full, but /var/log is empty. I think this happened when once the log was full and I deleted a large file.

vfrolov Posted October 4, 2019 Share Posted October 4, 2019 Got it. Looks like a bug lsof | grep /var/log ...... rsyslogd 1051 syslog 7w REG 254,0 18268 29 /var/log/syslog (deleted) rsyslogd 1051 syslog 8w REG 254,0 0 26 /var/log/kern.log (deleted) rsyslogd 1051 syslog 9w REG 254,0 44234481 22 /var/log/auth.log (deleted) in:imuxso 1051 1811 syslog 7w REG 254,0 18268 29 /var/log/syslog (deleted) in:imuxso 1051 1811 syslog 8w REG 254,0 0 26 /var/log/kern.log (deleted) in:imuxso 1051 1811 syslog 9w REG 254,0 44234481 22 /var/log/auth.log (deleted) in:imklog 1051 1812 syslog 7w REG 254,0 18268 29 /var/log/syslog (deleted) in:imklog 1051 1812 syslog 8w REG 254,0 0 26 /var/log/kern.log (deleted) in:imklog 1051 1812 syslog 9w REG 254,0 44234481 22 /var/log/auth.log (deleted) rs:main 1051 1813 syslog 7w REG 254,0 18268 29 /var/log/syslog (deleted) rs:main 1051 1813 syslog 8w REG 254,0 0 26 /var/log/kern.log (deleted) rs:main 1051 1813 syslog 9w REG 254,0 44234481 22 /var/log/auth.log (deleted) .... Perhaps, truncating the logs not syncronizeded properly with rsyslogd ... File i removed not from this list. restarting rsyslogd service solved the problem Link to comment Share on other sites More sharing options...
