If you set up the system on a RAID 10 and want to use that as well for the datastore, I would create a new ZFS dataset for the datastore. This allows you to change certain ZFS properties on that dataset specifically. There are a few things to consider if you want to have the OS on the same disks as the datastore. How fast are the disks? HDDs or SSDs? If they are HDDs, then having the OS on separate disks is a good idea because HDDs will already be having a hard time to provide the IOPS for decent performance. If they are *decent* SSDs, you should be fine. No idea how easy it is to get stuff in Croatia, but this should give you some ideas: https://geizhals.eu/?cat=hdssd&xf=2028_256~4643_Power-Loss+Protection~4832_1~4836_2&sort=r 250 GiB is plenty of the OS, but anything smaller is hard to find or of dubious quality ;) Cheers, Aaron On 2/7/22 01:10, Tonči Stipičević wrote: > I'm planning to use SUPERMICRO 721 box (4 x 2T sata) as PBS > > So, if I create zfs10 raid as boot drive , I have no more disks left for datastore, right ? > > BUT, is it possible to make directory on this / boot drive i.e. /mnt/datastore   and attach it as datastore ?   Is that a way-to-go  and is there any disadvantages against separate 2 x 240g ssd as boot and 4 x 2T sata (zfs raid 10 ) for datastore? > > Actually I'ma having hard time finding 2 x 2,5" small  sata drives for boot .... > >   Thank you very much in advance > > BR > > Tonci > > srdačan pozdrav / best regards > > Tonči Stipičević, dipl. ing. elektr. > direktor / manager > > SUMA Informatika d.o.o., Badalićeva 27, OIB 93926415263 > > Podrška / Upravljanje IT sustavima za male i srednje tvrtke > Small & Medium Business IT Support / Management > > mob: 091 1234003 > www.suma-informatika.hr > > > > _______________________________________________ > pve-user mailing list > pve-user@lists.proxmox.com > https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-user
