EXT4-fs error causing system to crash daily

[mimitair]

Dear proxmoxers

I have a proxmox installation on my old hp pavillion laptop. Currently it is running one debian container hosting a unifi controller. For the past three days, the laptop suddenly starts ventilating at full speed and crashing at (seemingly) random points in time.
The following error messages appear on the screen:

"""
[13467.016392] EXT4-fs (dm-1): failed to convert unwritten extents to written extents -- potential data loss! (inode 264736, error -30)
... (A couple more lines stating "[13467.016***] EXT4-fs error")
[13467.018504] EXT4-fs (loop0): Remounting filesystem read-only
"""

I've seen some related issues on the forum, but haven't really found a clean solution. Some stating to change the SATA cable, change SSDs... but since this is a laptop (and I am not qualified to screw around in it), I can't really make any hardware changes. Has anyone encountered this issue and/or know how to solve it? If you need more info on the errors, hardware specifications, log files... please let me know . Thank you in advance for your suggestions.

Kind regards

i got many error on this too, need to reboot the vm everytime it got RO. any clue yet bro?

 

[mimitair]

Yes, I need to hard reboot every time as well. No solution yet, going to have a look at it this evening.

@azkamstf, Unfortunately, I still have no clue. What hardware are you using? How often does this happen to you?

hey, try to update your bios. Proxmox kernels calls last virt libs, that need a good version of your bios

I have the same/similar problem with my n305 i3 NAS from CWWK. Runs fine for about 2 days then fs error with RO remount in my Debian VM. proxmox is not reachable anymore. Hard reset solves the problem but again only for 2 days.

If your ext4 FS remounts itself R/O, 99% your disk is dying. You need to replace it.

If you don't know how to change a laptop drive that isn't soldered in, there are youtube videos - and repair shops that can do it for you.

A dying ssd gives you i/o errors in 99%. I had 2 last month. In my case I the vm has a virtual disk so the error should be visible in the host. On the host the disk is on a zfs raid5. Don't understand your laptop comment.
