Great questions, 1) I have experience with zsf in a Truenas environment (my cli experience is limited) 2) zpool data lost of more than one disk would be disastrous 3) system would have 48gb of memory, my truenas box has 32gb and doesn't seem to bottleneck 4) don't want spun up disk 24/7 xfs has been rock solid, sounds like your saying "if it ain't broke"!

I have been running Unraid on xfs pool for seven years. Unfortunately the hardware setup afforded by my Dell Poweredge R710 is starting to show its age. More and more current day software is requiring chipsets not present in the Xeon X series of processor requiring me to either work around or abandon applications. The single parity drive setup has saved me and my data numerous time, the ability to use various size of drives in an array is game changing. But now I must upgrade! Moving to the Xeon E series process solves most if not all of my chipset requirement. Also I was able to remedy another problem replaced to the cost of running servers, drive replace cost. The R710 is 2.5 inch form factor. The cost of 2.5 inch disk have skyrocketed. The newer unit shifts to a 3.5 inch form factor reducing disk drive replacement cost by more than half. Which get me to why I am posting here: Under normal circumstances one would just pull the boot USB and all of the data drives, place them in the new unit, re-boot and be in business. But with the form factor change this isn't possible or (easily made possible). Since I am having to moving 10TB off the old array to setup a new array, it seems like a opportunity to migrate to zfs. Single parity xfs has been rock solid. Other than snapshots and replication Is this a lot of work for little reward?

thanks all, pulled usb drive and ran surface scan, no errors found flash drive still good. Recopied config from backup (in case something got corrupted). Reinserted, booted up and and all is good.

Unraid has been rock solid for me for years, other than the occasional hard drive failure. I recently (last week) replaced a corrupt flash drive. All was well until today when my system froze. The message from the system "The flash drive is corrupt or inaccessible". I have attached diagnostics hoping to understand the underlying issues before I start the paid process of replacing the flash drive, obtaining a new key and reconstructing the system.

yes flash is backed up

I am aware of the SSD read errors and do have a backup. It's part of a pool I just been procrastinating on the replacement. thanks

This issue is not isolated to the Nvidia plugin. I am unable to install or uninstall any plugin. Possibly a problem with the plugin installer.

I posted to the plugin section and was ultimately advised to post in the generation support area. https://forums.unraid.net/topic/98978-plugin-nvidia-driver/page/220/#findComment-1603022. Just looking for some help? mercury-diagnostics-20260119-1810.zip

My system has been running the Nvidia plugin for several years with no issues. Recently, last week, notification of a nvidia driver upgrade was implemented and issues pursued. It appears the new driver is not compatible with hardware. I have been working with https://forums.unraid.net/profile/72388-ich777/ hoping to resolve a problem with the Nvidia driver. I tried to remove the plugin and upon reboot it reappears. 1) with plugin (see screen shot below) one should be able to rollback by selecting previous version and clicking update (that does not work) 2) uninstall and reinstall plugin to reinitialize. It uninstalls but upon reboot is reappears. Hware: Dell Poweredge server GSU: Nvidia P2000. This should not be an issue, rollback to the previous working driver version and keep moving. Again,the plugin wont uninstall nor take change (rollback) to previous version.

attached is the diagnostics, also when I select a previous version of the driver I get the message attached earlier regarding v590.xx already downed loaded. it does appear to be something problematic with the plugin. mercury-diagnostics-20260119-1810.zip

From the plugin page I select v580 (open source) as its listed as an available driver and I get the attached. Remember I uninstalled the plugin, reboot and the plugin reappears after reboot.

attached is screenshot per your request. I also tried to remove the plugin, after reboot it reappears.

nvidia driver version 590.xx causes "NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running." hardware: Nvidia GPU P2000. tried to rollback to version 580.xx by selecting version in the nvidia plugin. System says 590.xx already downloaded. I guess asking how do I roll back to a previous driver version (580.xx seemed to work)?

Yes enabled writing to syslog flash

I enabled syslog prior to crash, should be writing to flash drive
