由于TrueNAS系统的处理方式,两个data vdev之间会以Stripe方式组成一个存储池。这个方案能够提供2盘的冗余,前提是故障的2块硬盘不在同一个vdev里面,而Raid Z2是可以提供存储池内任意两块硬盘的冗余的。 选择这样组建Raid,是为了后续扩容考虑。有了先前的教训,我意识到这个空间迟早得用完,只是时间长短罢了。而一旦组...
看来应该是truenas 共享的问题了，我ISCSI和SMB用crystaldisk mark测试读取有1.7G/S到2.5G/S，但是...
4.2 Meta Vdevs Meta Vdevs是近几年新出的一个功能。这个Vdev并不是一个缓存,而是一个Storage,因此,你需要确保这个Vdev有较高的安全性,比如两个optane硬盘组成一个Mirror甚至更大的冗余,如果这组Vdev坏了,在同一个Pool下的机械池数据也同样丢失。请不要想着试试看能不能用,操作不可逆。 Meta Vdevs解决...
用于主存储操作的标准 vdev。每个存储池至少需要一个数据vdev。 2)缓存 读取缓存与快速设备一起使用以加速读取操作。 TrueNAS存储顺序为内存->缓存存储池->数据存储池。 故使用大内存和大数据存储池可以有效提高数据存储行能。 官网原文 ZFS has several features to help improve performance for frequent access dat...
First I initially wanted to pass through the whole HBA but then I couldn't boot TrueNAS if I did that. I ended up just passing each disk one at a time. The performance is great, the scrubs and smart tasks are working fine, but there are two little quirks that I've noticed. One qu...
Replies: 10 Forum: Storage D Extend single disk to RAIDZ without losing data? Just wondering, I have a 2 TB disk which I use single right now almost 3/4 full with data. Can I add 2 x 2 TB disks and get a single-parity RAIDZ (raidz) configuration at 3 disks (2+1) without ...
Edit2: I ran the numbers, and while it's a more expensive option, I'm considering getting enough drives to create a 10 disk raidz2 1 vdev pool. I have 3 16tb exos drives on hand and would need 7 more. I can get refurbs from serverpartdeals, which I wouldn't normally do, but...

So if you have a three-disk RAIDZ1 vdev, you cannot turn it into a four-disk vdev. Uncle Fester's Basic FreeNAS Configuration Guide Unofficial, community-owned FreeNAS forum TrueNAS SCALE 23.10.2 SuperMicro X11DPH-T, Chassis: SuperChassis 847E16-R1K28LPB 2 x Xeon Gold 6132, 128 GB...
the system also didn't reboot this time, no output from running the import yet, system isn't totally hung but the webui doesn't load much if I open a new browser tab. I also checked the disk shelf and I don't see any drive activity lights for the drives in the pool. Do I wai...
