This article details how to solve one issue that may be stopping the Gaia web user interface from loading.
The login screen appears but after submitting your username and password, you get stuck on the spinning “flower of death”!
This can be down to a few different things but #1 is disk space – if the disk is full then temp files cannot be created and the webui will not load.
A simple “df -h” will tell you what’s going on:
[Expert@fw2:0]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg_splat-lv_current 11G 11G 0G 100% /
/dev/sda1 145M 19M 118M 14% /boot
tmpfs 980M 0 980M 0% /dev/shm
/dev/mapper/vg_splat-lv_log 11G 986M 9.2G 10% /var/log
Highlighted in red above we see the offender. Use “du -h” to find the directory which is taking up all the space – my issue was due to backups not being FTP’d off the machine from the “/var/CPbackup/backups/” folder. Once they were removed to free up disk space, everything was back to normal.
