g_vfs_done() errors on Dell/LSI RAID array

[Charles Sprickman]

Hello,

Not sure if this is the right place or if this is a geom issue, or a raid 
controller issue...  Please point me in the right direction.

Last night I saw the following in my daily output:

+g_vfs_done():mfid0s1g[READ(offset=2456998070156636160, 
length=16384)]error = 5
+g_vfs_done():mfid0s1g[READ(offset=2456998070156636160, 
length=16384)]error = 5
+g_vfs_done():mfid0s1g[READ(offset=2456998070156636160, 
length=16384)]error = 5

I'm a bit confused, as some googling indicated that this has something to 
do with a mis-labelled disk, but that offset seems really huge, unless I'm 
comparing two different units.

bsdlabel shows me this for that drive/array:

# /dev/mfid0s1:
8 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
   a:  8388608        0    4.2BSD     2048 16384 28528
   b: 12582912  8388608      swap
   c: 2928135357        0    unused        0     0         # "raw" part, 
don't edit
   d: 16777216 20971520    4.2BSD     2048 16384 28528
   e: 16777216 37748736    4.2BSD     2048 16384 28528
   f: 67108864 54525952    4.2BSD     2048 16384 28528
   g: 2806500541 121634816    4.2BSD     2048 16384 28520

Adding the size plus offset, the end of my disk should be at 2928135357. 
The offset in the error is 2456998070156636160.

Error 5 is apparently an "I/O Error".

This is a Dell 2970 running amd64, 7.2-RELEASE.  The RAID card is Dell's 
rebadged LSI:

mfi0: <Dell PERC 6> port 0xec00-0xecff mem 0xe9f80000-0xe9fbffff,0xe9fc0000-0xe9ffffff irq 37 at device 0.0 on pci7
mfi0: Megaraid SAS driver Ver 3.00
mfi0: 3049 (boot + 3s/0x0020/info) - Firmware version 1.22.02-0612
mfi0: 3050 (boot + 23s/0x0008/info) - Battery Present
mfi0: 3051 (boot + 23s/0x0020/info) - Controller hardware revision ID (0x0)
mfi0: 3052 (boot + 23s/0x0020/info) - Package version 6.2.0-0013

There's some talk in this thread about whether this is either a driver 
issue, a geom issue, a filesystem issue, some weird bug that people only 
see on 64-bit AMD procs, etc.:

http://old.nabble.com/g_vfs_done():da3s1a-READ(offset%3D81064794762854400,-length%3D8192)-error-%3D-5-td13199158.html

Any help tracking down what this is trying to tell me would be 
appreciated.

thanks,

Charles
