wapbl - Write Ahead Physical Block Logging

jmcunx

I just found out about wapbl and I enabled oy on my laptop, no issues so far, but would like a small confirmation.

I have cgd enabled on some file systems, in their fstab I added option "log". Are that any concerns I should know with it enabled on a cgd partition ?

As I mentioned above, AFAIK all is good after one day of use.

Thanks

My home server has been running on a CGD encrypted root with WAPBL enabled for years 😉

Thanks, I am satisfied.

This can be closed and marked solved, will try and figure out to do that 🙂

CGD is a layer below the file system - the kernel part isn't aware of file systems at all. FFS just sees a perfectly valid block device to make a file system on top of.
