Downgrade to the previous version if this is a production server to see if your containers can boot.

Don't forget the diagnostic file regarding this parity error

Through the GUI. The new config works too.

None, Jorge's description sums it all and else... I'll try to provoke this problem, voluntarily this time to explore and find answers.

I'm shocked regarding this news. Rest In Peace. Many'll miss you and thanks your work and your own being..

You can simply use GUI file explorer, or SMB share to manually copy your USB key content.

Not used to it, so I'll wait for another advice as I'ld simply "Tools -> New Config" to simply import the array again. However, I don't see any damage.

Can you share your diagnostic file please?

Shutdown Unraid, invert failing disk SATA cables and boot. And share your Diagnostic file please.

Remove the drives then? Else, you can use a liveUSB stick to boot on Windows directly.

Good evening! You can simply go to "Tools -> New Config". Assign only the new drive, after, and you can remove the previous.

Did you stop the Array before editing?

I've founded this too : Nov 16 01:06:41 Pasiv Parity Check Tuning: Paused Scheduled Correcting Parity-Check (2.5% completed): Following drives overheated: disk4(43C) Is this disk4 the new drive? 43°c is not specially hot and kinda, is it an HDD or an SSD?

Try to import each plugins folder one by one with a reboot. to notice wich plugin makes you not bootable.

Recreate without any data, boot, and check.

Did you create a vanilla USB Key without any data backed on it? Did you boot on UEFI or Legacy?

You can get an kind of ETA with the -v argument but need to keep the web console opened. The -P argument shall come within 2.4.

What a mess. @GRBHV5 Are you ready to recreate this pool properly? Could you supply 2 more nvme drives to speed up this pool? However, can you please share : ls /dev/disk/by-id/ Just to get an already prepared list of command for you, because I don't consider as a good practice to create pool with sdx names as you've no clue wich drive is concerned this way, and it's hardly exportable to another config.

Stop the array, so we're sure no depending files are locked in use and can be decompressed.

zfs set compression=none pool -r zfs rewrite -rv pool zfs rewrite -rv /mnt/pool Regarding ARC, this implies that you must keep a zfs pool with datas on it to be kept in RAM for read cache when a file is read/written.

Before doing so : zfs set primarycache=none pool -r zfs set compression=none pool -r zfs set direct=always pool -r zfs rewrite -rv pool So all your files shall be decompressed, ARC cache (ZFS proper cache within RAM) disabled, and you'll can give it another try. Else, if performances are still poor, you'll can move your datas already uncompressed peacefully.

Don't forget this too @Slippin' Jimmy using the -r argument makes it recursive to all your dataset. But that's weird for a cache pool to have many dataset.

When you edit this property, it only affects newly created files. Previous shall be decompressed after using zfs rewrite -rv (P argument to preserve files birthdate shall arrives with ZFS 2.4)

Don't use ZFS as a cache drive as you're already dealing with read cache within ARC. Use L2ARC else if your RAM is eaten by ZFS ARC. Disable ARC on your cache pool, check ashift argument is correct, for NAND, it's usually 13. zfs set primarycache=none pool -r zfs set compression=none pool -r If cache is NVMe: zfs set direct=always pool -r
