On critical daq servers (clondaqx) directory /et resides in ramdisk. Following have to be done during installation:

su
mkdir /et
mount -t tmpfs -o size=4096M xfs /et

To make it permanent, add following line in /etc/fstab:

 tmpfs   /etc   xfs   nodev,nosuid,noexec,nodiratime,size=4096M   0 0


General info

Check available memory size:

free -g

Example of creating 4G ramdisk and mounting it as /mnt/ramdisk:

mount -t tmpfs -o size=4g xfs /mnt/ramdisk

To make it permanent, add it to /etc/fstab:

tmpfs   /mnt/ramdisk   xfs   nodev,nosuid,noexec,nodiratime,size=4096M   0 0
