No Adapters Found Error: No MegaRaid Found


?!?!?! does that mean that there is no raid? why then the df output? the machine is supposed to have 4 250gig SAS drives.


Its more likely that megarc doesnt support the newer controllers which is a shame. you might have more luck with sysutils/linux-megacli since that explicitly mentions LSI MegaRAID SAS, I wish they would make the util open source though. Will mean you need the linux-base port installed and linux.ko loaded.

A RAID1 config shoudl suit a busy webserver well.

thanks...

hi all...

a hosting facility build a new dedicated server for me and looking at the dmesg i see:

mfi0: <LSI MegaSAS 1078> port 0xec00-0xecff mem 0xfc480000-0xfc4bffff,0xfc440000-0xfc47ffff irq 16 at device 0.0 on pci1
mfi0: Megaraid SAS driver Ver 2.00

for df i get:
Filesystem Size Used Avail Capacity Mounted on
/dev/mfid0s1a 496M 197M 259M 43% /
devfs 1.0K 1.0K 0B 100% /dev
/dev/mfid0s1e 496M 12K 456M 0% /tmp
/dev/mfid0s1f 661G 636M 608G 0% /usr
/dev/mfid0s1d 8.7G 1.4M 8.0G 0% /var


i asked for raid1. i cant find too much information about the mfi driver. just that it works with freebsd 7.


you might want to look at sysutils/megarc and possibly sysutils/linux-megamgr so you can more closely monitor/investigate your array.

i'll keep looking but - has anybody successfully deployed production servers using the LSI MegaSAS 1078 in RAID1 on a very busy web server?
is there any loss in performance using that hardware in RAID1?
any performance loss in RAID1 at all?


thanks...
