Hello
in a few threads it has been mentioned that in most cases using ext4 is faster and just as stable as xfs .
we've a 4 node ceph cluster in production for 5-6 months. our set up uses one osd per node , the storage is raid 10 + a hot spare . we use high end intel ssd for journal [ see anti-cephalopod mail threads on ceph users list ].
for increased reliability I want to put the journal on same storage as osd. the ssd's, even though they are considered to be the best model to have for journal ,are still a single point of failure .
so one node at a time I want to convert our setup .
could some suggest a standard procedure to change from xfs with dedicated journal to ext4 + journal on same storage?
should firefly be upgraded 1-st?
best regards, rob fantini
