ESXi v5.0 - Out of space error with more than 40GB of space reamaining

Jump to solution

I am currently running ESXi v5.0 setup in RAID5 with 146GBx3 (Total: 268.50GB)

I have added 2 virtual machines running all with thick

VM Machine 1 - HD1 Thin Provision (200GB Provisioned Size)

VM Machine 2 - HD1 Thin Provision  (33.91GB Provisioned Size)

VM Machine 2 - HD2 Thin Provision  (13566 GB Provisioned Size)

I then moved a VM Machine 3 from previous ESXi v5.0 to this ESXi v5.0 using "VMware vCenter Converter Standalone Client v5.0.1 Build-875114" (Thin Provision) which all went fine & has been running fine for many weeks.

But this morning I come in and see all the virtual machines stopped due to no space left I then checked the Vsphere Client & it said I had 40GB/268.50GB free in "Summary" - "Storage" & also in "Configuration" - "Storage" section.

Any ideas why this has occurred & how to minimize this happening again?

(I am still testing this but I think the cause was that ESXi free space did not change after using VMware vCenter Converter to add VM Machine 3)

Thanks

I never did a "Rescan All" is this not an automatic thing that should occur at least once a week or something?

They refresh periodically, but can sometimes get "sticky" and not update. The manual rescan (or two or three) will often refresh - I was just curious if you are really out of space of have 40GB free. You might also want to use the ESXi Shell to investigate.

Sorry I meant

VM Machine 2 - HD2 Thin Provision  (135.66 GB Provisioned Size)

NOT

Hello and welcome to the communities.

Did you rescan the datastores to see if the reported values changed?

With thin provisioning, it becomes critical to have some sort of monitoring to keep watch on the datastore free space. vCenter includes alarms, but if you don't have this you might have to look to 3rd-party utilities or a scripted solution.

Thanks for the quick reply.

I use spiceworks to monitor the disk space & advise me when it drops to 10% never got an email & spiceworks scans every 15 minutes and spiceworks still thought it had 40GB free which is why an alert was not sounded.


This is the event logs I got in VSphere ESXi

Even in ESXi alerts there was warning that it was going out of space as there was only 1 alert saying "out of space"

Thanks vmroyale for your help.

Will run re-scans on my other ESXi servers I have but I do think that the issue was after using VMware converter to move ESXi v5.0 to ESXi v5.0 that it never rescanned Smiley Sad

I will also check out the ESXi shell but I think I will call this closed becuase I can just manually run the re-scans if necessary.

Finally if I can prove that VMware converter was the cause of the issue I will see if I can submit a bug request to them.

Also on a seperate note is it worth upgraded all my ESXi v5.0 to ESXi v5.1 and is there much of a risk?

I'd say the risk is about the same as applying the regular patches that come out for vSphere 5. Definitely check out the release notes for 5.1, and also make sure that your hardware is still listed in the VMware HCL.

Thanks again vmroyale.

It appears the ProLiant DL360 G5 (Intel 5160) only support 5.0 U2 so looks like I cannnot go higher even though I have a single upgraded DL360 G5 (Intel 5160) runnning ESXi v 5.1 for many months without any noticable issues but it is only a test server to get access to Windows 8 Support Smiley Happy

It's odd though that they don't talk about E5430/E5435/E5335 but guessing they have to draw the line at some point otherwise they will be there for weeks writing the hardware requirement lists so far been running ESXi v5.0 on E series for 4-6 months now & it works fine.
