Hello,
One of my servers runs NetBSD-10.0 and panics if I try to use a ccd
device after a regular shutdown. I have to manualy run fsck on this
device (automatic fsck aborts), but I'm not sure fsck is enough (I have
seen a panic _after_ fsck). As this device only contains squid cache, I
prefer do a newfs followed by squid -z.
Server configuration :
legendre:[~] > df -h

Both wd0 and wd1 have been tested and don't have smart alerts. When I
restart this server, I can see a message just before system reboots. If
I remember, this message indicates that ccd0 is removed from system
before dk5 and could explain why filesystem is corrupted after next boot.
Same ccd0 device ran fine with -9.3 (but iSCSI initiator was broken, I
use -10.0 as a lot of iSCSI bugs have been fixed. Thanks.).
Best regards,
