Non-work banter and water cooler conversation
A place for non-work-related flimflam, faffing, hodge-podge or jibber-jabber you’d prefer to keep out of more focused work-related channels.

Hi everyone, Some time ago, we picked your brain on a question related to the number of Infrastructure as Code tools you were using on your infras. You were kind enough to answer this question and some of the key learnings we got came from here, so thanks a lot We asked this same question on several channels. For those interested by the outcome, here’s what we learned while digging into this question https://driftctl.com/how-many-iac-tools-on-a-single-infrastructure/

I use this in place of Make https://magefile.org/
I have created my atoms alike tool using Taskfile, and I guess you can do so using magefile, I liked the idea of atmos and why you need upper interface for all your internal tools.
I prefer Taskfile over other tools since it just a yaml file, and anyone can add and update their commands without writing any code.

i was chasing this gremlin in my home network for the last 2 weeks. if you combine this adapter converted from usbc to usba, plug it into a powered usb hub. then disconnect the usb hub from your laptop and leave the ethernet plugged into an unmanaged switch/consumer wifi router you WILL packetstorm and DOS your network but only once it’s NOT connected to your laptop
who can explain this??
Anker USB C Hub, 5-in-1 Premium… https://www.amazon.com/dp/B071G83L1J?
Anker 7-Port USB 3.0 Data Hub… https://www.amazon.com/dp/B014ZQ07NE
Syntech USB C Female to USB Male… https://www.amazon.com/dp/B085VT1VJT
I experienced something similar once on a network that spanned 30 or so buildings and dozens of switches and closets. I don’t know why it happened – when I found the ethernet dongle I cut it in half with my pocket knife. generally, plugging a USB hub into a USB hub rarely works as well as the USB standards would leave you to believe.

Hi All, Our kubernetes master node has 2 etcd volumesThey were working fine for almost 2 years One of the volumes has become read-only due to file system errors 2 weeks back
/dev/nvme1n1 on /mnt/master-vol-id1 type ext4 (rw,relatime,data=ordered)
/dev/nvme2n1 on /mnt/master-vol-id2 type ext4 (ro,relatime,data=ordered)
tune2fs showed the filesystem had errors
FS Error count: 4
First error time: Thu Jul 8 12:10:00 2021
First error function: ext4_journal_check_start
First error line #: 56
First error inode #: 0
First error block #: 0
Last error time: Wed Jul 21 16:57:50 2021
Last error function: ext4_remount
Last error line #: 4964
Last error inode #: 0
Last error block #: 0
Checksum type: crc32c
Checksum: 0xfb3bfe96
By checking online I found out that the solution was to unmount the filesystem and run fsck I unmounted the filesytem but when I ran fsck it showed the device was busy
# fsck.ext4 /dev/nvme2n1
e2fsck 1.43.4 (31-Jan-2017)
/dev/nvme2n1 is in use.
e2fsck: Cannot continue, aborting.
fuser and lsof commands show that it is not being used by anything
# fuser -cu /dev/nvme2n1
# lsof /dev/nvme2n1
the filesystem can by mounted read-only but cannot be as read-write
# mount -o ro /dev/nvme2n1 /etcd-events/
# mount -o remount,rw /dev/nvme2n1 /etcd-events/
mount: cannot remount /dev/nvme2n1 read-write, is write-protected
Is there any solution, I do not want to reboot the system as it will cause outage
