g_vfs_done errors

[PaulNYC]

I am seeing these errors on a lot (but not all) of my Vms, they all use the same EMC SAN for storage

these are freebsd boxes, running our web site

g_vfs_done():da0s1f[WRITE(offset=4625235968, length=16384)]error = 5

g_vfs_done():da0s1f[WRITE(offset=4625252352, length=16384)]error = 5

g_vfs_done():da0s1f[WRITE(offset=4625268736, length=16384)]error = 5

g_vfs_done():da0s1f[WRITE(offset=4625334272, length=16384)]error = 5

g_vfs_done():da0s1f[WRITE(offset=4625350656, length=16384)]error = 5

g_vfs_done():da0s1e[WRITE(offset=141885440, length=131072)]error = 5

any idea what causes them and how to fix them? What i see on google is potential problems with drives but as all my drives virtual, on the same SAN, i dont know what to think

Hello,

Where are you seeing these errors? On ESX, within the VMs, or on the SAN?

these are in the VMs. I have a dozen or so identical freebsd boxes running on esx3.01

Hello,

Review your vmkernel logs and see if you can correlate the FreeBSD issues to a an issue with your SAN/NAS device. It looks like your Guest OS is having disk issues which could be caused by an overloaded SAN, etc.

I was able to get a time on this happened as 3 of my boxes rebooted themselves as a result, and it was at 4am in the morning so nothing should have been doing much. I will check the logs and see. No chance of this being any issue with freebsd vms and vm scsi drivers?

Hello,

It could be but I would still investigate the vmkernel log file for issues first. I would not rule out anything at this time.
