PVA loads its home page forever after logging in, but it is possible to browse servers one by one, until a particular slave node gets hung and does not open its page as well.
When logging in to this stuck server, it is not possible to run
df command, it hangs:
[root@vz ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 15G 3.1G 11G 23% / tmpfs 3.9G 0 3.9G 0% /dev/shm /dev/sda3 273G 54G 206G 21% /vz ^C^C^C^C^C^C^C^C^C^C
There's a network share mounted on the server, which is inaccessible:
[root@vz ~]# mount ... //192.168.21.32/d$ on /mnt/share type cifs (rw,username=administrator,password=test)
A hung network (NFS/CIFS/etc) share doesn't allow PVA to obtain the information about mounted partitions on the server, therefore the server page hangs forever.
Resolve the connectivity problem with the network share.
