TrueNAS 12.0-U8.1 - Solaris: WARNING: Pool boot-pool has encountered an uncorrectable i o failure and has been suspend.

[hlggermany]

Hello,
i need your help! my Backup-TrueNAS has an error =>Solaris: WARNING: Pool boot-pool has encountered an uncorrectable i o failure and has been suspend.
after reboot=>

Controller was not found (LSI MegaRAID 9361-8i)

after a longer time power off, controller comes back und found all disks, but now the error comes back again
i can't type anything

How do I get back my data and the backup that are on the system?

I could plug in a USB stick and reinstall TrueNAS there. But I haven't saved the configuration yet

The current installation was done on an SSD in RAID1, but unfortunately this didn't work in the end.

What is the best way to proceed? can someone please help


thanks
Patrick

this information from me was wrong: The current installation was done on an SSD, but not on a RAID1

Welcome to the forums!

Sorry you are experiencing problems.

Please start with a detailed description of the hardware in your problem system, including information on the storage and boot drive disk controller(s) and that for the drives also.

TrueNAS System
LSI MegaRAID 9361-8i
HDD Toshiba 300GB 10K SAS (RAIDZ2)
SSD Samsung 480GB (RAIDZ2)

when i reset the server over IPMI, LSI Controller does not come back. I will quickly order a new controller
when i turn off the server over IPMI, wait and start again, the controller boot and find the disks

when booting

but now nothing

i wait for the new controller and hope i will be boot.

You flashed it to IT mode, right?

What's all the noise about HBAs, and why can't I use a RAID controller?

1) An HBA is a Host Bus Adapter. This is a controller that allows SAS and SATA devices to be attached to, and communicate directly with, a server. RAID controllers typically aggregate several disks into a Virtual Disk abstraction of some sort...

I'm curious to see how this evolves. I haven't heard of anyone actually having issues (other than performance issues in some scenarios) with the mrsas stack. I don't know enough about the RAID controllers to know whether to be worried, but the fact that the controller was spitting out messages about mfi is a bad sign, independently of any immediate problems here.

Mistake #1?

LSI 9361-8i poor performance

Probably not the right place to post but i need some help with hardware based raid. I want to build a FreeNAS box but don't feel comfortable yet with the OS. Any way, my current setup is using windows 7 and I'm experiencing very poor speeds with the LSI 9361-8i Raid card i have tried different...

#SOLVED
Change RAID Controller => it works.
