Failed to execute command

so I mounted a new hdd and I'm wiping it. Now what should I do to avoid losing the shared folders with the relative permissions that I had created on the broken HDD?

not possible, you need to recreate one at a time on the new HHD.

And be carefull to delete old shares to avoid problems.

Thank you, then I delete all shared folders and all samba shares.

Do I recreate from UI again?

YES

Which filesystem do you recommend to avoid stress to the data hdd?

BTRFS ; for a single Disk use single mode, DUP mode reduce the size of available data to 1/2 because DUPlicate all data on disk (good to have 2 copies for redundant reasons)

on BTRFS disk, you can create shares that are in fact a new subvolume so you can do snapshot that do not fill space on disk, you can do snapshot daily, hourly, etc. in my case that I use data disk for series & Videos, I do weekely snapshots

raulfg3 sorry, I solved it, I first had to delete all the samba shares, then all the shared folders and then I was able to unmount the filesystem. Can I create a new filesystem now or do I have to delete/adjust something else?

I'm noticing something, is it possible that OMV exchanges the names of the disks, i.e. /dev/sda with /dev/sdb?

you can create a new filesystem now, no need more.

no problem if OMV exchange names i.e. /dev/sda with /dev/sdb because, OMV DO NOT use this names, instead use UUID that never changes. like: /srv/dev-disk-by-uuid-005aeda9-b65c-4f6c-9b6d-9ab6bf9dbc07/Data/Backup

Thanks. What does shares that are in fact mean? Where are these snapshots saved?

please read about snapshot and his magic ( no free file space ocupied).

eg: https://fedoramagazine.org/working-with-btrfs-snapshots/

please edit your signature with spec of your NAS, (Motherboard, CPU,RAM, Power suppply, connection whit DISK )SATA or USB) etc...). Because I do not know that important info , I can't imagine what the cause, if you use Raspi or simmilar, a common cause of broken HDD are fault/exhaust power supply.

Other common cuase is excess of Temperature, are your disk well airflow?

it's happening again, the hdd is breaking, then I want to understand the reason because this is the second hdd that has broken.

I don't want to start from scratch to create folders, permissions and shares so I'm asking you please for a method that saves all the configuration in a place external to my NAS.

use backup described here: https://wiki.omv-extras.org/do…v7:utilities_maint_backup

or here: [How to] Migrate/Restore OMV Settings to Another System with omv-regen

there is dust, not directly on the hdd but in the fan and the cpu heatsink.

please try to check the rel temperature, use a termometer or simmilar or try to monitorize on OMV WebGUI if HHD temp excedd from 65ºC : 70ºC perhaps your problems reside on that point. and check power supply too, as i say commom error are a excesive low power supply to power the HHD.

for SMART error 187 i find this:

2. **Error Code 187**: This error signifies an unexpected power loss or a power loss event that the hard drive has detected. It's an indication that the drive has encountered a sudden power interruption.

and one more suggest: experiment, try options and if not work, start again, only trying and testing, you can understand what happen eg:[How to] Migrate/Restore OMV Settings to Another System with omv-regen
