Performing verification for Jammy.
I started two Jammy VMs. One is a server and the other a client.
Server
------
$ sudo apt update
$ sudo apt upgrade
$ sudo apt install samba
$ sudo vim /etc/samba/smb.conf
[sambashare]
comment = Samba on Ubuntu
path = /home/ubuntu/sambashare
read only = no
browsable = yes
$ mkdir ~/sambashare
$ sudo smbpasswd -a ubuntu
Client
------
$ sudo apt update
$ sudo apt install cifs-utils
$ mkdir ~/share
$ sudo mount -t cifs -o username=ubuntu //192.168.122.172/sambashare ~/share
The client is using 5.15.0-102-generic from updates:
$ uname -rv
5.15.0-102-generic #112-Ubuntu SMP Tue Mar 5 16:50:32 UTC 2024
$ sudo -s
# while true; do echo "$(date) hallo" >> ./share/hallo.txt; sleep 1 ; done
Launch a separate terminal and run:
$ df -h ~/share
df: /home/ubuntu/share: Resource temporarily unavailable
The issue is seen.
I then enabled -proposed and installed 5.15.0-105-generic.
I had to use the -proposed2 repository due to the packages not being present
in the primary archive -proposed repository.
https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/proposed2
$ uname -rv
5.15.0-105-generic #115-Ubuntu SMP Mon Apr 15 09:52:04 UTC 2024
$ sudo -s
# while true; do echo "$(date) hallo" >> ./share/hallo.txt; sleep 1 ; done
$ df -h ~/share
Filesystem Size Used Avail Use% Mounted on
//192.168.122.247/sambashare 9.6G 2.1G 7.5G 23% /home/ubuntu/share
CIFS is back to working again, and we can df the share and see the disk
usage.
The respun kernel in -proposed fixes the issue, happy to mark verified
for Jammy.
