Additional HDDs Pool?

[Fyodor]

Hello! I'm having a FreeNAS file storage built at the old ATX system having 5 x 500GB HDDs set into one pool. Can I add another 4 x 3TB HDDs to the same system and mount them into separate RAID5 pool? Thanks for answering!

 

[melloa]

Everything is possible, but you need to provide more information about your system. Also check the Resources tab above and the pinned posts on this same sub-forum. See picture.

 

[Fyodor]

OK. I check resources but can't find similar topic so far. Can I generate a file giving system description?

 

[Ericloewe]

You want Cyberjock's guide. Check my sig.

 

[gpsguy]

Volume manager is your friend - check the docs for help.

The simple answer is yes: If your hardware has enough ports. You can have more than 1 ZFS pool in the system.

 

[Fyodor]

Great! Thanks for answering, IceBoosteR. Obviousely to install 4 HDDs into the system with 5 HDDs already present I need some investments, so I needed to know these capabilities upfront. I will go by installing Silicon Image Sil3114SATA PCI controller as existing system board doesn't have 4 SATA ports available.

I will go by installing Silicon Image Sil3114SATA PCI controller

This is a really bad idea. Search the forums for a proper HBA for your system.

Also the fact that you are considering purchasing a PCI controller card makes me suspect of the rest of your system. What is your hardware configuration that FreeNAS is currently installed on?

 

[Fyodor]

Sorry, I'm not a pro in this.
Here is my configuration:
FreeNAS-9.10.2-U1 (86c7ef5)
Gigabyte GA-M59SLI-S5
AMD Athlon(tm) 64 X2 Dual Core CPU
6 GB DDR II
ZFS vol 1: 5 x 500 GB Seagates RAIDZ1
ZFS vol 2: currently 3 x 3 TB WD Greens RAIDZ1 at ST Lab A-214 PCI SATA 4 Channel Card
Transcend 8 GB USB 2.0
Aerocool KCAS-800W

There is a 4th 3 TB WD disk (all 4 purchased together and were in use before) to organize pool 2 having 4 discs. But smartd reports on 312 unreadable sectors, so I took it out. This volume is new and empty, so I can easily reset it as needed.

 

[Jailer]

You're under the minimum spec on RAM by 2GB. 8GB is the minimum. I hope you don't have any important data on this system.

 

[Fyodor]

Yes, I'm under, these were all DDRII chips I could find around. Before adding new discs system was working well and stable for many years (used mostly in weekends, but still). For Windows based systems we consider that RAM defines mostly the "speed" of operation. Does RAM defines also a data reliability at FreeNAS?

 

[Fyodor]

DDR2 DIMM chips are about $20 on a market. Perhaps I will go buy one next week.

 

[Jailer]

Does RAM defines also a data reliability at FreeNAS?

It most definitely provides system stability. I would definitely add more especially since you are planning on expanding your pool.

 

[Fyodor]

OK, I will. How about PCI SATA card? It can support RAID 0, 1 and 0+1, but this was not an intention. Intention was to physically install all 4 additional drives. I did not install any drivers from CD or network (should I?). All HDDs are seen thru this card and can be mounted into the pool. One out of four has shown unreadable (pending) sectors right after initial installation, but does it have any relation to switching it thru PCI card - doubt it. I will need to check this disc to see if I can use it at all.

 

[Jailer]

Can you view smart data with that card installed?

 

[Fyodor]

I have started smartctl long check for suspected HDD installed thru card. Will be out of server for a while and can check result on Thursday. I had some issues with email setup, it was not complete. How can I see smartctl results then?

 

[Fyodor]

Hello!

First of all RAM has been increased to 8 GB yesterday to meet minimum requirement. I know ECC is recommended, but this will require a full replacement, so I will try to solve it later.

On HDDs. I have four 3 TB WD Green HDDs physically connected thru ST Lab SATA Card. And I keep receiving the following system message on one of them every 30 min:

Code:

Feb 25 13:29:06 freenas smartd[2383]: Device: /dev/ada8, 312 Currently unreadable (pending) sectors

smartctl -t long /dev/ada8 command has been started and test has passed in full. If I'm not mistaken, to get the result I need -a attribute.
Here is the output:

May I use this ada8 to switch it into zpool or something bad is starting to happen with it?

 

[Fyodor]

Sorry for reminder, could somebody take a look at smartctl report above and let me know if HDD is still good for usage or not. I was thinking to switch 4 HDDs in mirror, but if one is out then it needs to be changed. Thank you.

The drive is full of pending sectors and is waaaaaay too hot. Not good.

 

[IceBoosteR]

Hi,
as cooling for drives is everything (I also need a new case), some temperature about 35 degrees would be nice.
The pending sectors are maybe an indication for prefail, but I found this regardings the sectors:

In general, the "Current Pending Sector" is a temporary issue only. If the block will be replaced form the spare pool, the "Reallocated Sector Counter" will increment, resp. the number of spare blocks decrements.
