Diagnostic Tools for VMFS File System?

CnicNV

Hello all,

I am wondering if it is possible to diagnose or run some sort of check disk on hard drives running VMware's VMFS file system?  Or is this something that would be automatically reported in events and alerts in vcenter server console for each host?  Or does VMFS automatically handle bad sectors and should I rely on out of band server diagnostics tools to check hard drive SMART status etc?

Thanks

what version of ESXi are you using ?

Bad Sectors would usually be handled by your storage controller, and RAIDED disks?

So you are not using ESXi on a single disk SATA system? e.g. non-RAID ?

The virtual file-system is best tested by the guest OS using that file-system, just like it would be without any virtualization in place.

Thanks, I sorted this out.  Coincidentally I just happened to check the vkernal logs and they were littered with errors similar to the ones in that troubleshooting link you posted.

Also, I used the Dell server diagnostics tool (F11) and the suspected single hard drive did in fact fail a few tests.  Ahh well, I have backups of these VMS, so I will just move them to another hard drive.

Need a budget for a SAN lol...ugghh

You don't need a SAN, just make sure you use RAID 6!

What sort of Enterprise virtualisation service do you offer, with VMs on a single disk!

LOL, tell me about it, preaching to the choir.  Not something I have any control over.  I just need to make it work with what I am given.

However this is only for development, not production and whatever it is, I would not call it enterprise :-P

Thanks again:-)
