Reccomendations Concerning Disk Filling

[pirateghost]

Pool. Free space in the pool.

Based on his comments, I bet he has a different pool for every disk.

Why? I have no idea why someone would do that. He has zero redundancy or data protection....

@pirateghost

The data protection is on external hard disks in another town. I prefer that instead of RAID in case of fire or thieft.

@depasseg

What do you mean? Can you please tell me if no matter the disk size, the recommandation is alwase 100 GB, for me thats make sence but I think its not this I should understand.

 

[depasseg]

I don't know how to say it any clearer. Pool.

Please post the output of zpool status in code tags.

You obviously still do not understand what ZFS is or how it helps you. Your backups are BACKUPS, not redundant disks.

I have a hard time understanding how you have been a member of these forums for so long and know so little about how FreeNAS benefits you....You should be using ZFS and RAIDZ(or mirrors) for your data. You are using FreeNAS in a completely incorrect fashion.

 

[depasseg]

The size is based on your workload and anticipated file deletion size. Some people do 20. What is the size of your pool?

@pirateghost

Im happy with FreeNAS even if use it in that way. I use it in that way for years now without any issues.

@depasseg

That is the output of the zpool status

My pools size is entire drives so this is mean 7.25 TB per pools (8 TB HDD).

 

[pirateghost]

I can't even comprehend the logic behind this setup.

 

[depasseg]

You have a 24 bay server with one drive?

@pirateghost

I live in a appartement block, you know, so its more possible there was a fire since we are all packed together, its normal we are to packed since its a appartement building, so if one put fire into his unit, all the block can burn down, I know about fire wall between each unit but I prefer take precautions.

I am not talking about a fire at all.

You are not thinking about this the correct way.

RAID is not backup, ZFS is not backup. You have BACKUP disks that hold your data elsewhere in case of a fire. This has NOTHING to do with what I am talking about.

If you read the powerpoint presentation or read any documentation on FreeNAS you would understand what ZFS and how it benefits you. I don't think you get it at all.

@depasseg

No no, I have a 24 bays server chassi but each drive is, I don't find the words for describe it, but each disks is not in a RAID, thats mean I see all the 24 disks in /mnt . Hope that help.

 

[depasseg]

The statement that you take precautions, yet have a pool with a single drive does not compute. But my recommendation still holds. If course, since you only have one drive it's likely that you have nearly synchronous replication right (to your alternate site)? In that case if your 8TB completely fills and therefore is destroyed, you could at least recover from backups.

@depasseg

this means that you have 24 individual POOLS, as each drive has to be a POOL. Your zpool status says otherwise though....

The fact that you are less concerned with a drive failing and more concerned with your apartment burning down causes me great worry for your safety.

@depasseg

So, did you think 100 GB of space reservation per disks is correct in my case if I put 8 TB HDD in the server?

@pirateghost

I have only one disk at the moment, but it fit 24 disks my server chassi.

you are contradicting yourself in nearly every post......

you said you had 24 disks just a few minutes ago, and now you say you only have one disk....

obviously with one disk you could never do a raid anyway, so I don't even know why you speak like this. Just say 'I HAVE ONE DISK', not "I have a 24 bay chassis and every disk is no raid"

 

[guillaumesoucy]

Yes, I should say this on the begining, its my fault. Sorry, my english is not at 100% :)

When I saids 24 Disk, I mean the server can contain this amount of disks. But I currently have one disk.

 

[pirateghost]

I realize you may not understand the terminology, but it is VERY important that you get it correct. Technical subjects like this are extremely important to understand the terminology associated with them. If you tell people the wrong phrase, it means something COMPLETELY different. It could mean disaster for your data if you say the wrong thing.

Take the time to learn the language, and express your posts and comments with correct terminology, otherwise, you get loads of MISINFORMATION because you did not specify correctly what it is you need/want.

Or post in another section of the forum that is in your native language so something doesn't get lost in the translation.
