raid

This is a strange one: I've recently reinstalled FreeBSD 14.0 on an old, non-mission critical PowerEdge R710. Two zpools were created, zsystem and zdata. Since the old BIOS doesn't give me a JBOD option, the pools were created with megaraid virtual devices all attached to the same controller...

Hello my new friends, it’s me again, I am now on day 3 of FreeBSD and I have almost set up all the important bits. I set up a RAID1 for my 2 disks that hold my home directory per the handbook, and then set up a geli partition on that mirror device as described in the handbook, and then I put...

Hi, I want to setup a new home office workstation using FreeBSD. My main requirement are low noise and large storage. Data redundancy is required as the data is intended to be stored for a long period of time, and it is mostly write once and read many -in case it matters for the RAID...

Hi, I have 5 old disks each of them of different size, cache, date of production and even vendor. How can I "truncate them to provide redundant storage"? is it even possible? Or I should buy 2 same brand new disks?

Hello! I have two gmirrors on my machine. Both are showing up as degraded. These are brand new drives that I just installed (so I don't mind blowing up the configuration and re-doing things). I followed this guide to get going as I have no experience with gmirror...

I’ve got 4 3tb 7200rpm drives coming and the plethora of options for raid have me scratching my head in wonder and confusion. I can use y’all’s help... I want to be able to lose a single drive and be ok. I also want the fastest possible write performance. I’m ok sacrificing read performance...

I have created a patch for the 'ciss' device driver that allows FreeBSD to talk to HP SmartArray/SmartHBA RAID/HBA controller cards that fixes a number of problems we have had with it on our systems (HP servers with the HP SmartHBA H241 controllers and multiple HP D6020 external SAS disk...

Hello. My software raid 5 rebuiled hot and after that there are penging somewhat. Does anybody knows what does it mean "Pending"? Geom name: Data State: COMPLETE HOT Status: Total=8, Online=8 Type: AUTOMATIC Pending: (wqp 11 // 2) 2052749657088..2052749661184/4096p...

Hi I am a Data Recovery engineer and this is my first post here and also the first time I work on raidz, I got a customer needs to recover data from damaged NAS storage with 36 hard drives. I have a good experience recovering data from Other types of raid like 5, 10 etc, but this is my first...

Hello, Running FreeBSD 11.1-RELEASE. I recently purchased a 3ware 9690SA-4I4E controller to swap into of my SQL server but have run into an issue. When I put the 9690SA-4I4E card in, the controller's BIOS shows all the drives are available but marked "offline". I've been looking for a method...

Hi everyone - We're working on a setup that requires a RAID controller to setup 4x 2TB SATA drives in a RAID 5 configuration. This will need to be compatible with FreeBSD 11 as well. The controller we had on hand unfortunately only has drivers up to FreeBSD 9 so we're stuck having to purchase...

I guys, hope you can help me. I have a HDD which was previously in a RAID array. Now I wanna used it alone as Master (IDE hdd)... For now I managed to switch it from CABLE SELECT to Master and BIOS is showing it up in list of device. I'm using lastest FreeBSD usb bootable to try to format this...

Hi there, one of our FreeBSD system fails to boot with following errors: (da0:mps0:0:1:0): READ(10). CDB: 28 0 52 47 5f df 0 0 80 0 (da0:mps0:0:1:0): CAM status: SCSI Status Error (da0:mps0:0:1:0): SCSI status: Check Condition (da0:mps0:0:1:0): SCSI sense: MEDIUM ERROR info?:c0010000 asc:0;0...

Dear FreeBSD users, Recently, I was working towards setting up a new zpool at work with freshly salvaged Western Digital and Seagate SATA hard drives (all 500 GB). However, FreeBSD 11.0-RC2 detects the drives as elements of bigger raid arrays (r0 and r1) in the arrangement 2x 500 GB + 2x 500...

I have 128GB HDD on my HP proliant, it is running in raid 1(2x sas). But my bitcoind server is using most of it and I get messages that the drives are full. So I bought 2 500GB sas drives. I want to run the 4 drives in raid 1+0. But I don't want to lose my system because it will take a long...

Hello,who can explain what is meaning "Non-medium error" in this output. I think my hard disks have some problems. Disk1 root@nshost2:/home/david # smartctl -a -d cciss,0 /dev/ciss0 smartctl 6.5 2016-05-07 r4318 [FreeBSD 10.3-RELEASE-p4 amd64] (local build) Copyright (C) 2002-16, Bruce Allen...

I have a Dell PowerEdge R200 running FreeNAS 9.10 with an Adaptec 1045. I have 4 1 TB SATA Drives on the Adaptec controller. The drives are recognized in the BIOS, but not by FreeNAS. On Adaptec's website there are drivers for Suse and Red Hat, But I can't install any RPM's on FreeNAS. There...

I am in the process of migrating to UEFI on my laptop. I would like /boot to be on a separate partition in order to have / on GELI, but I cannot get the UEFI bootloader to play along. It finds both my mirrored /boot UFS partitions just fine, but refuses to continue because /boot/loader.efi does...

I'm setting up a RAIDZ2 pool on a NAS I've built and I have one disk throwing the "GPT Invalid or corrupt" error. As I understand it, I can use ZFS on raw disks without partitioning and would prefer, if possible, to just remove the partition table on this disk (or all of my disks, for that...

My home server currently runs CentOS 7 but I'm going to be moving to FreeBSD in the near future. The most important thing my server does is act as a fileserver, using four 4TB disks in a RAID10. This is pretty easy to do in Linux with mdadm, and after it's built you just use mdadm --detail...
