Hey all. Can someone tell me, when installing XCP 1.6 what size partition does it require the basic install? By that I mean not VMs etc, just the basic XCP installation itself?

Below that and the install failed. I don''t know what the exact number is but I learned to set the disk size to 30 just in case. The OS drive partition however is only 4 GB.

Thank you Sébastien. I have an HP DL160 server with dual quad core CPUs, 12 Gb of RAM. The machine has a pair of 120Gb SSD drives and a pair of Western Digital 1Tb GP4 hard drives. Its main function is to replace a Windows 2003 server which has a 40Gb operating partition, and a similar sized data partition. On the OS partition it currently runs a mail package, and the data drive contains just websites. The machine also runs MySQL. How would you suggest I best configure the new server? Although it has a RAID card, it isnt my intention to use RAID at all though I am open to suggestions. I will create a Windows Server 2008 VM. Im guessing I will need this to have at least some storage on the actual hard drives for its swap file. Am I best to run Windows from the SSD or to have the Windows installation on hard drive too? I dont really know how much benefit Id see from having the Windows system files on an SSD. My assumption is that its the website datafiles, and the datafiles for MySQL that will benefit most from being on the SSD, but Im happy to be told Im wrong. How would people suggest I best configure this drive wise? The machine will obviously be running more VMs in the future but to start with its the one VM that I need running correctly and efficiently. Thanks for reading this. Regards, Chris.

There was a thread about it not long ago: http://lists.xen.org/archives/html/xen-users/2012-08/msg00166.html Also, there was a hardcoded restriction of the minimum size of the target hard disk at 16Gb. Although, it''s fairly easy to patch it. google: "xcp min_primary_disk_size" Note, I''m talking about XCP 1.5 here, have not seen 1.6. -- Alexandre Kouznetsov
Hi, Yeah that''s true, now I remember (sorry had forgot it) that it creates at least a backup partition to store full .tar.gz backups of the system. So yes in Chris case, I would definitely not install xcp on the SSD and save its life and space for io intenseive stuff in the VMs. Cheers, Sébastien On 06.12.2012 19:29, Alexandre Kouznetsov wrote:> Hello. > > El 06/12/12 12:11, Sébastien RICCIO escribió: >> It usually creates a 4GB partition >> >> [root@xcpsanbox ~]# df -h >> Filesystem Size Used Avail Use% Mounted on >> /dev/sda1 4.0G 2.2G 1.7G 57% / > > I have not installed 1.6 (yet), but if I recall correctly, XCP 1.5 > created at least 3 partitions: one for "/" of 4G, another one of the > same size (unused) and the rest of the disk was dedicated to LVM. > There was a thread about it not long ago: > http://lists.xen.org/archives/html/xen-users/2012-08/msg00166.html > > > Also, there was a hardcoded restriction of the minimum size of the > target hard disk at 16Gb.

Hi, Initially I had intented to mirror the drives onto their twins but I couldnt decide how likely I felt an SSD was to fail. I assume you are suggesting using RAID 1? I did consider using RAID 1 for the two hard drives and RAID 0 for the SSDs. I guess it comes down to reliability figures that personally I dont really know. Thanks again, Chris.

Not doing this you''re taking a chance to loose data in case of a drive failure. For the XCP setup, I think I would install it on the 1tb drive, then create a XCP storage repository using the rest of the disk. Then create another storage repository using the SSD drive(s). Then depending your needs your can create non IO intensive virtual machine disks on the mechanical drive SR (storage repository) and IO intensive on the SSD one. In a same virtual machine you can attach disks from both of the SR. Why not installing XCP on the ssd drive? I dunno that could be an idea too, but as far as I know the SSD drive have limited write life, so i think it''s maybe not an idea to use them for the xcp parition that constantly write logs ... Well that''s how I would do it, but there might be better ideas :) Cheers, Sébastien On 06.12.2012 19:23, Chris Long wrote: Thank you Sébastien.
