Hello Chris,

Looks like the database was already on the SSD before my tmpfs
experiment.
--8<---------------cut here---------------start------------->8---
mathieu@berlin ~$ df -h
Filesystem Size Used Avail Use% Mounted on
none 95G 0 95G 0% /dev
/dev/sda1 916G 321G 549G 37% /
/dev/sdb1 37T 34T 2.6T 94% /gnu
tmpfs 95G 8.0K 95G 1% /dev/shm
tmpfs 10G 2.4G 7.7G 24% /var/lib/cuirass_tmpfs
--8<---------------cut here---------------end--------------->8---
I don't really get why I/O pressure on /dev/sdb could impact /dev/sda.
Thanks,
Mathieu
