    LSI HBA Firmware vs Driver Version

    LSI SAS 9207-8i IT Mode LSI00301 Info: Should I update the firmware version at all? From what I have gathered by reading through forum posts is that if I see "mps" I am in luck as my LSI HBA card is definitely flashed to IT Mode. I am currently troubleshooting slow raid-z2 SMB read speeds...

    No Raid 10 option

    I have 4 disks (4x1 TB) which I was planning to set up as raid 10...Is this just terminology ? I spent some time lookig through forums, and this seems like it is not an option .. I only see the Raidz2 option, but it doesn't seem the same as Raid 10 ... It doesn't really matter to me - I am...

    TRIM support, and any other issues to look out for in an all SSD pool?

    I'm planning to build an all SSD pool for various storage (vm's, database, static files etc...), and I often run in to the TRIM-thing and garbage collection painted as a big issue with SSD's. I'm not sure if this information is obsolete or not. The FreeNAS documentation does not help me that...

    What Performance Can I Expect?

    Hi, I have used FreeNAS for a while now for home storage and Plex use but recently I was able to take home from work an HP server and a storage shelf. I have 30x 600GB 10K 2.5" drives in these systems total and all in one raid, RaidZ2. I was wondering if someone knew what the max read/write...

    Optimal setup for Veeam backups ( 12 and 24 drive )

    Hello, I'm hoping to get some advice on how to properly configure the volumes on two new freeNAS devices. We always receive our NASes with a pre-configured volume setup, see attached. We prefer RaidZ2, and I've recently read that you want your vdevs to have a number of drives equal to a power of...

    Replacing a faulty drive from a raidz2 array

    I have a raidz2 array of 6 x 4tb wd reds. One of the drives are now reporting smart failures so I contacted the retailer for an rma. They would like me to send in the drive for evaluation and repair. Freenas would report the array as degraded when I remove the drive, but would it be fine to run...

    raidz2 keeps crashing during resilver process

    I have a raidz2 in FreeNAS 11.1 that has been running great for quite a while but I noticed the other day one of my drives was beginning to fail as the Offline_Uncorrectable value began to steadily increase over the past couple days and had gotten to about 9k when my new drive arrived.

    FreeNAS zPool adding disk question.

    I am purchasing an HP DL380g8 with 12 drive bays. I want to start off by doing a raidZ2 with 4 drives, then have the ability to add a single drive to the pool for space, not caring about having additional redundancy. Is it possible to create a raidZ2 pool with 4 drives, and just add drives to...

    Effective storage space

    Hi everyone, So a quick back of the napkin question here - I have a freenas server with 8 4TB drives setup into one raidz2 volume. Now, some very rough calculations would give the machine 32TB of raw storage space to begin with, then subtract 8TB for the raidz2 - leaving 24TB. Again, rough - I...

    Is my RAID-Z2 correct?

    Hello, i migrated from CentOS file server RAID5 (4x4TB) to FreeNAS with same disks few days ago. Changed to ZFS and created RAID-Z2. Today I added fifth 4TB drive and expanded volume as a "stripe". I feel it was wrong choice be cause the new drive shows up separately as "stripe". Can someone...

    raidz2 + encryption + faulted drive; re-importing & resilvering 11.1-U4

    Hello so I have an encrypted raidz2 pool with a faulted drive (da0). I wanted to upgrade the entire array, but ran into snags. What I did was, detach the entire array, reboot, and attempt to get the new drives to work. The new 12TB SAS drives appear to not spin up; I think that is a "pin3...

    Creating a temporary (transit) backup of a raidz2 volume.

    Hi all, I've got a FreeNAS 11.1 file server, which I'm shipping to New Zealand (I'm moving there). It has a single raidz2 volume, based around 4 1TB SSDs. As insurance for the data, I've bought 4 new 1TB SSDs and my intention was to create a backup. I thought the correct way to do this was to...

    SOLVED raidz2 seemingly doesn't have 2 disks of redundancy?

    I have a raidz2 that I've had to replace a couple disks on. It consists of 8 6TB drives. That stuff all looks okay to me, but under the storage tab it shows that I'm using 29.2 TB and 14.3 TB free (43.5 TB total). FreeNAS says that a 6 TB drive yields about 5.46 TB. At 8 drives that...

    Hi all, I am running FreeNAS-11.1-U1 and have 16 (1.5 and 2.0TB mixed) drives in a raidz2 pool. I recently had what I believe to be a faulty sata cable causing a device to pop online and offline over and over again. I have replaced the affected disk and the sata cable and it has left my pool...

    Abysmal performance for write speed within RAIDZ2 pool

    I noticed an issue with my rsync speeds to my RAIDZ2 pool. I typically would've gotten 50MB/s but now I can barely write more than single MBps. My pool is nearly 100% capacity so I expected some performance degradation but I still have 150GBs of free space and not for my performance to fall...

    I'm putting together a FreeNAS server and before purchasing drives I have one question please : Would 5 x 4tb or 6 x 3tb drives be a better configuration for RAIZ2 with >10Tb of usable storage. Both will achieve my capacity amount and I would prefer to use less drives but if 6 drives has a...

    I'm on a budget and only have 5 3TB Hard Drives lying around, but I want to at least get 12TB of storage.

    SNMP OID for usable Amount on Pool

    Subject pretty much explains it. But here is what is happening. I have an 8 disk (6TB/disk) Z-RAID(2) setup and when I do an SNMP walk on the FREENAS-MIB, I always get the total disk-space for the pool instead of usable disk-space.

    7 vs 6 Drives and RAIDZ2

    I'm building up my FreeNAS server and I found a way to squeeze and extra drive into the case for a total of 7 drives instead of 6. I had planned on using RAIDZ2. Is it still adequate to use RAIDZ2 if I use 7 drives? Also, is there any issue with having a odd number of drives with RAIDZ2? Thank...

    Hi All, New to freenas and NAS in general. I have setup a nas using initially 6 drives (4tb Ironwolfs).
