-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I found some discussion about this in December, but I don't think anyone has been able to get to the bottom of it yet. The symptom is that processes become permanently blocked in a state of ufs or getblk. I can reproduce it with find at will: % ps axl | grep ufs 0 13225 13215 1 -4 0 1300 804 ufs D ?? 0:00.96 find /var -xdev -type f ( -perm -u+x -or -perm -g+x -or -perm -o+ 0 28778 28765 0 -4 0 1300 804 ufs D ?? 0:00.97 find /var -xdev -type f ( -perm -u+x -or -perm -g+x -or -perm -o+ 0 33017 32933 2 -4 0 1304 788 ufs D p2- 0:10.69 find / -name samba It has also happened several times in single user mode to makewhatis running at the end of installworld. System details: 5.2-RC FreeBSD 5.2-RC #1: Fri Jan 9 04:45:51 EST 2004. Dell PowerEdge 2500. All filesystems are on a single raid 5 volume using the aac driver. The box has two CPUs, but I'm currently running with kern.smp.disabled=1. % mount /dev/aacd0s1a on / (ufs, local) devfs on /dev (devfs, local) /dev/aacd0s1e on /usr (ufs, local, with quotas, soft-updates) /dev/aacd0s1d on /var (ufs, local, soft-updates) procfs on /proc (procfs, local) linprocfs on /usr/compat/linux/proc (linprocfs, local) I also have ACLs enabled on /usr, if that's at all relevant. The kernel has DDB and DEBUG_LOCKS. Please let me know if there's anything I can do to help debug this. I don't know if this is related, but another problem is that when shutting down, it always gives up on a bunch of buffers. I think I've seen over 100, but usually it's 4-10 buffers. - -- Lachlan O'Dea Computer Associates Programmer tel: +61 3 8416 5627 fax: +61 3 8416 5810 mobile: +61 412 390 650 odela01_at_ca.com Relax and enjoy your shoes! -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (Darwin) iD8DBQFABipaoBZahcUBONoRAqPFAKCZQZUJrTYIxOMJmwCHt7RPamn//QCeJlMJ bXdcm6vr+Z7nBoPSqWQU3ds= =H80i -----END PGP SIGNATURE-----Received on Wed Jan 14 2004 - 20:51:29 UTC
