No, bluestore_fsck_on_mount_deep is applied when bluestore_fsck_on_mount
is set to true only.
Hence there is no fsck on mount in your case.
Thanks,
Igor

restarts
Hi Samuel,
wondering if you have bluestore_fsck_on_mount option set to true?
Can you see high read load over OSD device(s) during the startup?
If so it might be fsck running which takes that long.
Thanks,
Igor

Dear folks,
I had a strange situation with 3-node Ceph cluster on Luminous
12.2.12 with bluestore. Each machine has 5 OSDs on HDD, and each
OSD uses a 30GB DB/WAL partition on SSD. At the beginning without
much data, OSDs can quickly up if one node restarts.
Then I ran 4-day long stress tests with vdbench, and then I
restarts one node, and to my surprise, OSDs on that node takes ca
15 minutes to turn into up state. How can i speed up the OSD UP
process ?
thanks,
Samuel
