RAIDZ1 + ssd cache + ssd log
4 drive-2 TB-WDC_WD2003FYYS ( worked on average more than 5 years)
+ Nvme Samsung_SSD_970_PRO_512GB
Sunday night hanged the server.
Soft reboot didn't help, did the reset
Failed to load.
Connected the monitor and saw that the download could not be read in the sector.
Booted from the stick and ran the program in Victoria drive which was the problem .
Smart stated that there are 1 unstable sector.
Tested and reassigned it ( only 1 sector).
Not having completed the test drive - again tried to boot in Proxmox
Below are attached screenshots.
Tried different ways to mount the pool - does not work.
At the moment, ends up creating a full backup of the disk images using ddrescue
That's what it became.
/dev/disk/by-id/ata-WDC_WD2003FYYS-02W0B1_WD-WCAY00923792-part3 disk could zabekapit only 99.9 %
Hundreds of readable sectors.
3 disks have the same TXG ( one of them broken)
1 Disc has its own TXG ( the disc itself is read)
Created disk images.
Mounted these images
losetup /dev/loop1 /opt/ata-WDC_WD2003FYYS-02W0B1_WD-WCAY00923209-part3.bin
losetup /dev/loop2 /opt/ata-WDC_WD2003FYYS-02W0B1_WD-WCAY00925258-part3.bin

losetup /dev/loop4 /opt/nvme-Samsung_SSD_970_PRO_512GB_S463NF0ka29555r-part2.bin
Tried the PR utility to rollback to the total TXG
Then tried to mount the pool with an indication that TXG
zpool import -fF -XT 922580 -o readonly=on rpool
zpool import -fF -XT 962577 -o readonly=on rpool
The computer "thought" day, but then still couldn't mount the pool
On this pool I essentially need to pull 2-3 of the image and possible backups.
Are there any repair utilities?
This prog can "see" my pool
But it is paid and not the fact that recover.
Gives a lot of errors, can not be considered pool
With this script and could not understand to the end. Documentation at a minimum :-(
Fork of the previous project.
Documentation more, but also not fully clear how it works.
Why it starts a local server it is not clear how to run the script.
Maybe there are some ways to recover data from razvalistoj ZFS RAIDZ1 ?
What can you recommend?
