Lots of Reads on Boot Flash Drive

Featured Replies

Hi all,

I have constant reads of the flash drive on my v7.3.0 server.

This is with 10hours uptime:

inotifywait --timefmt %c --format '%T %_e %w %f' -mr /boot

shows constant reading of config files from shares and plugins:

Does anyone have a clue what this could be?

Thanks in advance!

Update: it seems to have taken care of itself...

over night, the writes have more than tripled, but it looks like it calmed down and is stable now

Do you run a backup script or plugin or the flash backup feature from the Management Access page in the settings?

Hey @MowMdown - very good catch!

I figured the same: I actually run some Borg Backups and had the verbose option set. I removed that after my last post and the reads have calmed down a lot, so that must have been it.

I had to replace some defective hardware and inspected everything very closely afterwards and thats why i cought the issue now. I think this has been going on without me noticing it for a while now :D USB-Stick still working, though

Thanks for confirming my suspicions! Ill mark your post as solution for now :)

@MowMdown I was too quick, the reads are still there. But it indeed only happens, when Borg is running.

The weird thing is, it is not backing up the flash drive / boot at all, just the stuff on the array and caches.

Do you have any idea, what the issue could be?

The backup script just starts borg and backs up all data to a remote ssh host.

Can you share the backup script?

Thanks for looking into this!

See attached file for the backup script.

I use it with the unassigned devices plugin.

When I plug in an external HDD, it gets mounted and the script runs (gets called via UD).

backup.sh
