big dbus problem,need some help

wrc1944 · Last edited by wrc1944 on Tue Jan 02, 2024 11:21 pm; edited 1 time in total

Dbus-daemon failed to start, message bus failed to bind socket /tmp/dbus c9tgf0sft

read only file system. Ran fsck maually and fixed a bunch of file system errors from orphaned

corupted file list

Could anyone clue me in on what’t going on? This was after a normal world update. I think, on a pipewire/wayland/x11 system (not using wayland)

Rebooted and it seemed to help, but today i‘t’s back again can’t open anything, then reboot can’t do anything. Can open recovery kernel, but not sure how to proceed. Looked at some relevant forum posts which said unmerge dbus, remove etc/dbus-1 directory, re-merge dbus solved,and also mentioned doing etc-update

(maybe I missed that?
A few posts I looked at:

You need to solve your read only filesystem problem first. Dbus needs to create a socket and can't do so on a read only filesystem.

Are you shutting down dirty every time due to a hang? You're using a journalling filesystem (btrfs? ext3fs? ext4? xfs?)

Did your system create the /run and /var/run -> /run directory? (/run should be tmpfs, not on your rootfs)

Don't know what doc you read for unmerging dbus, this would probably not be helpful or clean for that matter (if you force removed it)...

eccerr0r is right, fix /tmp, it should never be mounted read only, typical to set to 1777, no suid, no dev. but needs to be executable (for some things that write there)

dbus wiil try and put the socket in /tmp, without the socket it won't work.

wrc1944,

/tmp should be in tmpfs in RAM, not on your HDD.

Thanks much guys.

I'm using multiboot setup, only can boot gentoo in recovery kernel, some commands fail. even if I have difficulty I can access gentoo logs or info from another distro.

Gentoo is completly is on its own sda-8 partition.

I'll get back with more info hopefully in a day or 2.

This an many years old system running perfect until last week world update. I did just realize it is an etc3 file system! have been using ext4 on all my installs for 15 years.
NOT shutting down dirty every time due to a hang, just typing reboot in terminal, works perfec

/run and tmp are there, and var/tmp is there, with 101 items

/var/run is a link to inode directory

I accessed the gentoo partition logs from my linux mint partition, and the last dmesg showed no errors.

My other identical gentoo install runs perfectly. but doesn't have the tmpfs line in fstab, which surprised me.

is the tmpfs file in this fstab wrong?

This is the current gentoo fstab on /dev/sda8 ( the commented out sda 4 and 9 are just old removed distos)

More info. Booted 4 times did world updates partway but always hangs with fs and inode errors fixed with fsck, but also having input-output errors opening stuff.

cleaned up fstab, seemed to help. gentoo is on sda8 on this multiboot, where Mint grub is the loader for evry thing else. The dmesg is today's, and no errors I could see. going back in to try to finish @world Will post cleaed up fstab later

P.S.: Is this line complete (or truncated from copying) ?

must be a copy/paste problem. I eas just doing rest of a world update, and qtwebengine finished, then it locked up again with:

pietinger,

Forgot to mention that I've never used initramfs since making Gentoo ~amd my main Distro for over 20 years, as it's optional.

Also, the fstab I posted isn't up to date. I cleaned it up commenting out partitions that no longer are active, or even currently exist (the/dev/sdb partition).
I'll post it again shortly.

Having a stable and working hard drive would be the first issue to solve before blaming dbus, i/o errors to the hard drive is not a good sign. Checking its SMART info would be interesting, perhaps this thread is more a hardware problem than a dbus/software problem...

Here's some Smartctl info. Hope I did it correctly. I was surprised it didn't have lots of errors, but I don't know how to interpret the results.

Also, after my last reboot after a full fsck file and inode fixes run, gentoo booted and I could finish the @world update, but then hung on input-output errors again.

On the next reboot, I got this, which might help find the problem.

" fsck start /dev/sda contains a file system with errors, check forced
/dev/sda deleted inode 2457 has zero dtime FIXED
/dev/sda inodes that were part of a corrupted orphaned list found

FSCK MANUALLY

Aborting

What orphaned list would that be referring to, and if it was removed might that help?

pietinger, do mean you need to see my kernel .config file?

When dealing with SMART self-tests, I take the position that an error is presumed critical unless it can be explained.

I would have preferred a long selftest instead of the short one, but even the short one appears to have found a problem. Therefore, I concur with pietinger: you should expect this drive to continue to exhibit crippling failures, and it may become worse with no further notice. If you do not have a recent backup of this drive, your first order of business should be to make a backup of anything you would regret losing. If you do have such a backup, I encourage you to validate that the backup can be restored to a clean drive and has the important data. I would remove this drive from service as soon as possible.

Hu, here's the long version. using the command from the gentoo wiki. I expected a lot more data for an 80 mimute run. Did I do something wrong?

Silly question, have you tried pulling the sata cable loose from both ends and resetting OR try with another cable?

Edit to add: I would also pull the power cable from the drive and reattach, I've seen electrical connections build up oxidization over time and some just pulling and reattaching fixes that problem. Doesn't mean the drive is good though, so backup if possible is still recommended.

Thanks very much everyone. Looks like a new drive is in order asap, and backing up my data to external media.
This a linux multi boot drive, and I was wondering if I could avoid a new gentoo install, and clone an image of the gentoo partition over to the new dive, or even the entire drive
with the ther distros partitions? I have installed gentoo and cloned stuff many times, but not in about 10 years (just turned 80)

Are we thinking my problems are probably NOT the gentoo installation per se, but likely entirely hard drive related?

All the distros are in their partition, inside a large sda3 extended partition.

On the other hand, one more point to mention is that for years none of the other distros have ever had any problems like the ones gentoo has recently.
And, my other identical gentoo on another system runs perfectly

Guess I can stll do a full new install if it comes to that,before I really get too old. :roll:

heh, I play with fire on my disks. Still milking the last few puffs of magic smoke left in one of my 2TB drives that currently has 62096 power on hours, 411 reallocated sectors, and 163 sectors pending remap (and a whole bunch of read failures in the test log)... So far it's behaved since I did its last intervention, though it only is a 1.2TB disk at the moment, running 24/7 as a scratch disk. Yeah I back it up onto my raid just in case...
