      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Thank you for the response.&lt;/P&gt;&lt;P&gt;I think you have pointed the mistake.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;STRONG style="font-size: 11px; font-family: 'Courier New'; color: #000000;"&gt;9 &lt;/STRONG&gt;is the number of the new partition (1-8 already exist except 4). I don't think the mistake is here.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;STRONG style="font-size: 11px; font-family: 'Courier New'; color: #000000;"&gt;115087360 &lt;/STRONG&gt;is the value of the first sector i choose. Basicly, i did the last of partition 3 (the max one) and +1. The value of the last sector (&lt;STRONG style="font-size: 11px; font-family: 'Courier New'; color: #000000;"&gt;157030400&lt;/STRONG&gt;) is first + 20*1024*1024 (for 20 Go).&lt;/P&gt;&lt;P&gt;Obviously, my calculations are completly wrong !&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I followed the document you have linked and i understood difference between bloc of 128 and 2048. But i don't understand how to calculate the first and the last value of sectors.&lt;/P&gt;&lt;P&gt;have you an advice please ?&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thank you.&lt;/P&gt;&lt;P&gt;Regards.&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Apologies if I should be starting a new thread for this instead of reusing this one.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I am running into the same issue, using ESXi 5.1 u1 on Dell poweredge R320, using local storage (two disks hardware RAID 1, so ESXi sees a single 500GB disk)&lt;/P&gt;&lt;P&gt;This is a freshly installed ESXi 5.1 with no datastores currently set up. I am trying to create a single VMFS5 datastore that spans all remaining available space so I can start deploying VMs.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Here is my disk layout:&lt;/P&gt;&lt;P style="padding-left: 30px;"&gt;&lt;SPAN style="font-family: courier new,courier;"&gt;&lt;STRONG&gt;~ # partedUtil getptbl /vmfs/devices/disks/naa.6b8ca3a0e6df030019482dcc149c8519&lt;/STRONG&gt;&lt;/SPAN&gt;&lt;BR /&gt;&lt;SPAN style="font-family: courier new,courier;"&gt;gpt&lt;/SPAN&gt;&lt;BR /&gt;&lt;SPAN style="font-family: courier new,courier;"&gt;60734 255 63 975699968&lt;/SPAN&gt;&lt;BR /&gt;&lt;SPAN style="font-family: courier new,courier;"&gt;1 64 8191 C12A7328F81F11D2BA4B00A0C93EC93B systemPartition 128&lt;/SPAN&gt;&lt;BR /&gt;&lt;SPAN style="font-family: courier new,courier;"&gt;5 8224 520191 EBD0A0A2B9E5443387C068B6B72699C7 linuxNative 0&lt;/SPAN&gt;&lt;BR /&gt;&lt;SPAN style="font-family: courier new,courier;"&gt;6 520224 1032191 EBD0A0A2B9E5443387C068B6B72699C7 linuxNative 0&lt;/SPAN&gt;&lt;BR /&gt;&lt;SPAN style="font-family: courier new,courier;"&gt;7 1032224 1257471 9D27538040AD11DBBF97000C2911D1B8 vmkDiagnostic 0&lt;/SPAN&gt;&lt;BR /&gt;&lt;SPAN style="font-family: courier new,courier;"&gt;8 1257504 1843199 EBD0A0A2B9E5443387C068B6B72699C7 linuxNative 0&lt;/SPAN&gt;&lt;BR /&gt;&lt;SPAN style="font-family: courier new,courier;"&gt;2 1843200 10229759 EBD0A0A2B9E5443387C068B6B72699C7 linuxNative 0&lt;/SPAN&gt;&lt;/P&gt;&lt;P style="padding-left: 30px;"&gt;&lt;/P&gt;&lt;P style="padding-left: 30px;"&gt;&lt;SPAN style="font-family: courier new,courier;"&gt;&lt;STRONG&gt;~ # partedUtil getUsableSectors /vmfs/devices/disks/naa.6b8ca3a0e6df030019482dcc149c8519&lt;/STRONG&gt;&lt;/SPAN&gt;&lt;/P&gt;&lt;P style="padding-left: 30px;"&gt;&lt;SPAN style="font-family: courier new,courier;"&gt;34 975699934&lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Looks like partition 3 does not exist in the partition table above, so I am going to pick that as my partition to create.

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Apologies to have not answering on the answer of AT10.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;And thanks for these answers, AT10 and AakashJ.&lt;/P&gt;&lt;P&gt;the command &lt;SPAN style="font-size: 11px; font-family: 'Courier New'; color: #000000;"&gt;partedUtil setptbl "/vmfs/devices/disks/naa.600605b00581fb6018c09f852081693a" &lt;/SPAN&gt;&lt;SPAN style="font-size: 11px; font-family: 'Courier New'; color: #000000;"&gt;&lt;STRONG&gt;gpt&lt;/STRONG&gt;&lt;/SPAN&gt;&lt;SPAN style="font-size: 11px; font-family: 'Courier New'; color: #000000;"&gt; "9 115087360 4087881694 AA31E02A400F11DB9590000C2911D1B8 0"&lt;/SPAN&gt; didn't work either.&lt;/P&gt;&lt;P&gt;Same error of Read-only.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I decided to give away on multiple partitions because of this : &lt;SPAN style="color: #000000; font-family: 'Courier New'; font-size: 11px;"&gt;VMware do not support creating multiple vmfs partition from single disk.&lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;I had extended the last partition to &lt;SPAN style="color: #000000; font-family: 'Courier New'; font-size: 11px;"&gt;4087881694&lt;/SPAN&gt;. by this command : &lt;STRONG style=": ; font-size: 8pt; font-family: 'courier new', courier;"&gt;partedUtil resize "/vmfs/devices/disks/naa.600605b00581fb6018c09f852081693a" 3 10229760 4087881694&lt;/STRONG&gt;&lt;/P&gt;&lt;P&gt;then i created one datastore&lt;/P&gt;&lt;P&gt;&lt;STRONG style="font-size: 8pt; font-family: 'courier new', courier;"&gt;vmkfstools -C vmfs5 -b 1m -S DATASTORE /vmfs/devices/disks/naa.600605b00581fb6018c09f852081693a:3&lt;/STRONG&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;For my initial problem, i decided to use new hardrive in the VM and use multiwriting and then create the partitions in it.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;To answer to AVT123, your command seemed correct.&lt;/P&gt;&lt;P&gt;It's similar to my case except i did a extension where you tried to create another partition.&lt;/P&gt;&lt;P&gt;Do you try with another partition number as 9 per example ?&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Regards.&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Thanks for the reply, Ludovic.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I did try to create the partition with # 9 instead of 3, and received the same exact error. Interestingly enough, I am able to create the datastore via vSphere client, and it creates a GPT with the same exact parameters I provided in my command line.&lt;/P&gt;&lt;P&gt;My goal is to automate this process since I have to do it on 50 servers, so figuring out that last piece of the command line to get it working would be super helpful.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I should also specify that I am running this command after SSH-ing in to the ESXi server as root - should I be enabling a specific mode or anything like that before running my command? Should I not be running this command while SSH'ed in?&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Old, old thread, I know. But I spent some hours with the same problem and finally found the solution, so in case someone finds this thread by searching...&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;The error with &lt;SPAN style="color: #000000; font-family: 'Courier New';"&gt;partedUtil setptbl &lt;/SPAN&gt;resulting in&lt;SPAN style="color: #000000; font-family: 'Courier New';"&gt; &lt;SPAN style="color: #000000; font-family: 'Courier New';"&gt;SetPtableGpt: Unable to commit to disk&lt;/SPAN&gt;&lt;/SPAN&gt; is "simple":&amp;nbsp; setptbl seems to require to specify the ENTIRE partition layout, so &lt;SPAN style="color: #3d3d3d;"&gt;all existing&lt;/SPAN&gt; partitions with all their starting end ending sectors etc., plus the one you want to create.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;But, luckily, that is not necessary if you just need to &lt;EM&gt;add&lt;/EM&gt; a partition at the end (or probably also in between, if there's space). Just use&lt;SPAN style="color: #000000; font-family: arial, helvetica, sans-serif;"&gt; &lt;SPAN style="color: #000000; font-family: 'Courier New';"&gt;partedUtil add&lt;/SPAN&gt;&lt;/SPAN&gt; instead and it should work!&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;P&gt;Thanks, that helped ). I didn't have to reinstall ESXi on my home lab server ).&lt;/P&gt;</description>
