Subject: how does the caching works in bcachefs
Date: Wed, 08 Jul 2020 23:46:00 +0200 [thread overview]
Message-ID: <2308642.L3yuttUQlX@t460-skr> (raw)
Hello,
short question: how does the caching works with bcachefs? Is it like "first in first out" or is it more complex like the ARC system in zfs? The same with the write-cache, will be everything written to the SSD/NVMe (Cache) and then to the HDD? When will will the filesystem say "its written to disk"? And what happens with the data on the write cache if we have a powerfail?
And can I say have this file/folder always in the cache, while it works "normal" ?
Thanks in advance!
best regards
Stefan
