Hi,
I've also seen this "kernel: kern.maxpipekva exceeded, please see
tuning(7)" on the console of our Dell PE6650, which (again) had lost its
amr (LSI RAID/Perc). This machine isn't under load but runs rsync every 5
minutes.
amr0@pci3:1:0: class=0x010400 card=0x05181028 chip=0x19601000 rev=0x01 hdr=0x00
vendor = 'LSI Logic (Was: Symbios Logic, NCR)'
device = 'MegaRAID'
class = mass storage
subclass = RAID
# uname -srm
FreeBSD 6.1-RELEASE-p3 i386
... with just this KERNCONF:
include GENERIC
ident PE6650
options SMP
options COMPAT_FREEBSD4
options COMPAT_FREEBSD5
The amr seems more stable since "Scott's Mega Update" (see: http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/amr/amr_cam.c?rev=1.15.2.1&content-type=text/x-cvsweb-markup&only_with_tag=RELENG_6_1_BP )
but probably under high load or after a while it still fails (no disk
access possible, no messages).
Has anyone else running a Dell PE6650 with this LSI RAID?
Anyone else got this errors?
Regards
Raphael Becker
