HAMMER2 issue ?

[Laurent Vivier]

Hello Matthew,

Thank you for your answer, I'll then wait for the destroy-inum functionality shipping with the next release.

Have a great day and thank you for your awesome work on DragonFly !

CRC check failure on two inode blocks.   This has happened to me once too, I've been trying to track it down.  It is possibly related to unclean shutdowns but it isn't supposed to happen on H2.

In terms of fixing it, it shouldn't hurt per-say (other than not being able to access whatever files those two inodes are associated with), so you can probably wait until the next release cycle to get the hammer2 directives that can destroy the inodes.  Those are in master now (the hammer2 destroy-inum directive).  Any related 'dead' directory entries can also be located and destroyed via the existing hammer2 destroy directive.

Hello DFlyers !

I got these errors spamming dmesg and my boot TTY although the system seems to be running just fine, is this something I should worry about or correct ?

I _think_ those are HAMMER2-related but I am unsure

My root filesystem is HAMMER2, installed from a DragonFly 5.2.1 system now running 5.2.2

Have a great day,
