How come and you create 100G and the available space is bigger than what you created. Does that mean that it has created a portion of a 200gb disk which is 100gb? Why the amount of space used (103Gb) is bigger than what is created. Which values give you the assumption of zvol is empty? Is it...

Anyone ...

Hello I d like your opinion about setting up of the second raid storage of the server. So here is what I ve got so far The first quadrant sas hdds are being setup as raid10 zfs and are going to be used for VM's, one of them would be WinSer2019 (I ll explain below why I am mentioning the...

Thanks for the command even though I remembered I ve done the same before 2 years when Prox didnt have the GUI option of zfs mirror creation, but I did it for 4 drives (even though after your advice it seems quite logical to just add the third drive to the stripe before issuing the mirror...

This seems a better way to go than lowering the ashift and also if for 100gb it takes as much space then you are talking about 1-1 here, Nice even though I think I ll create a raid 10 for sata drives also. Do your numbers still valid? By the way you cant delete a zfs raid type from GUI are you...

I came to that conclusion too,since one Vm would be for SQL Server 19 adn another one for A.D / DNS / DHCP Server, but since I ll give portions of the same raidz disks I cant change volblocksize for each VM. If I set it once that s it to my understanding for the future VMs to be created.

Thank you very much for your time and effort helping me out . I just hope since never changed the default allocation size of Win before installation to let OS be installed on such a formatted Vdisk. just reminding you here in case you overlocked that there is a possibility those sas drives...

Hi again. I ve read the article and since yesterday that I posted in this thread, kept reading a ton of stuff which only lead to confusion, There are plenty of users that need a theoretical good advice for their hardware / needs (that means to provide this stuf first) and have an advice from a...

Since you seem to have a way better understanding on that subject and me getting lost trying to figure it out by myself reading random posts here and there which in most cases makes things worst, in case you could help here is my case The Server will have 4 (6gps sas 10K rpm) 1.2Tb disks in zfs...

Even though you are not referring to me and this is true for the Linux OS block size, my intention is for Win VMs so the filesystem will be NTFS / 4k (at least I think WinServ19 still using that) So bottom line Hdd's with 512b logical and 4k physical Compression lz4 on So which ashift and...

Which means that you loose how much of the available space? To my understanding there is no way to set parameters in a way you dont loose any size except the one you lose due to parity reasons. i mean 4 drives of 4Tb, instead of 16Tb you go with 7.2 with RaiZ2 and you lost this way some Tbs...

@Fabian_E Is the type of zfs raid relevant to the number which needs to be setup for the volblocksize? For instance i have a zfs2 (4 drives) and another member adviced me to <<Also keep in mind that you need to increase your volblocksize before creating your first VM or you will waste alot...

Actually raw is 14.5Tb and usable is 6.83Tb. Thank you for the clarification of the diffrence between zpool and zfs list. That is the plan actually. For data I have 4 x4Tb NAS drives 7200Rpm (Red Pro and IronWolf Pro) in what I thought to be best Raidz2 (do you advise otherwise? The data to...

No other than I want to know once more ...... I like the edit part

I managed to create a zpool consisting of 4 x4tb drives and gave me all the possibilities before creation even raidz2. i was going for Raid10 but better to be able to loose any 2 drives than 2 specific ones (so data integrity more critical here than performance). Weird thing is I was expecting...

Thanks but there got to be a way to check it

I d like to know which is the type of compression used when you set it to auto upon installation, since running the command :~# zfs get compression rpool NAME PROPERTY VALUE SOURCE rpool compression on local doesnt give any...

Pretty sure as you can see in the attached picture zfs_member.jpg I just re installed prox using uefi and (probably should have mentioned it earlier in case it matters) during installation as in the previous install attempt, I used advanced and se 100gb from the 128gb for over-provisioning...

Hello I ve recently noticed 3 things with my 2 SSDs running in mirror created during prox installation. First I noticed that in the GUI -> Node->Disks, under the tab usage each ssd has the <<partitions>> word (installation made with mbr method) In another proxmox installation again with...
