I was vaguely aware of GPT but I've never used parted before just now. I know GPT is (generally) needed for disks larger than 2TB, but should I use it all the time now, even for virtual disks inside a Xen VM? </span></font><div><br><div style="color: rgb(0, 0, 0); font-family: arial, helvetica, sans-serif; font-size: 12pt;">For that matter, if I'm creating a virtual disk to give to a VM, is there any reason to partition it with anything? I've been creating one partition and then creating the filesystem in the partition. I just create separate virtual disks for what I would have used partitions for in the past--so for example the main OS is on one virtual disk, /opt is on another, and each disk has one partition. I saw a btrfs tutorial yesterday where they were just using the whole unpartitioned disk, and it made me wonder why I was should partitionVM disks, other than habit.</div><div style="color: rgb(0, 0, 0); font-family: arial, helvetica, sans-serif; font-size: 12pt;"><br></div><div style="color: rgb(0, 0, 0); font-family: arial, helvetica, sans-serif; font-size: 12pt;">On GPT / 2TB drive limits, how can you tell if the hardware & BIOS will support GPT and/or drives larger than 2TB?</div><div style="color: rgb(0, 0, 0); font-family: arial, helvetica, sans-serif; font-size: 12pt;"><br></div><div style="color: rgb(0, 0, 0); font-family: arial, helvetica, sans-serif; font-size: 12pt;">The lsblk looks very cool, ty DJ!</div><div style="color: rgb(0, 0, 0); font-family: arial, helvetica, sans-serif; font-size: 12pt;"></div><div style="color: rgb(0, 0, 0); font-family: arial, helvetica, sans-serif; font-size: 12pt;"><br></div><div><font face="arial, helvetica, sans-serif"><span style="font-size: 12pt;">Scott</span></font><br><br><font face="arial, helvetica, sans-serif"><span style="font-size: 12pt;">p.s. I just learned that fdisk was patched in June 2012, for v2.3.1, to support GPT! Of course, that's of little use to me since CentOS 7 still has 2.23.7 as the latest available version.</span></font><br><font face="arial, helvetica, sans-serif">https://git.kernel.org/cgit/utils/util-linux/util-linux.git/commit/?id=766d5156c43b784700d28d1c1141008b2bf35ed7</font></div><div><font face="arial, helvetica, sans-serif"><br></font><hr id="zwchr" style="color: rgb(0, 0, 0); font-family: arial, helvetica, sans-serif; font-size: 12pt;"><div style="color: rgb(0, 0, 0); font-family: Helvetica, Arial, sans-serif; font-size: 12pt; font-weight: normal; font-style: normal; text-decoration: none;"><b>From: </b>"DJ-Pfulio" <DJPfulio@jdpfu.com><br><b>To: </b>"Atlanta Linux Enthusiasts" <ale@ale.org><br><b>Sent: </b>Friday, October 14, 2016 6:23:17 AM<br><b>Subject: </b>Re: [ale] Xen Server adding a virtual disk to a VM<br><br>fdisk doesn't handle GPT partitions.<br>Use parted instead.<br><br>lsblk<br>lvs<br>vgs<br>pvs<br><br>are handy too.<br></div></div></div></div></body></html>
