swap partition VS swap file

Swap File:

1. If the hard disk is full or corrupted,swap file will get damaged.

2. System speed get decrease as soon the hard disk space is full.

3. It should be on a particular location where it should not get damaged or accidentally copied with other files.

4. It have advantage to increase the swap space on a system that have already installed with linux.

5. In any case if we need to increase the swap space of the system immediately we can do it.

6. We can able to create and keep the swap file on external device.

7. New kernel have nearly achieved to make both swap partitions and swap file speed closer.

8. Swap file will get fragmented.

Swap Partition:

1. Reside on a separate hard disk space.

2. Multiple Os on a single machine can share the same partition.

3. Fragmentation is less compare to swap file.

4. If hard disk is corrupted the swap partition would not be functioning.

5. Reduce accident loss or corruption.

Resolved: DOCKER: Error response from daemon: Could not attach to network / rpc error: code = 7 desc = network not manually attachable.

I got this error: 'docker: Error response from daemon: Could not attach to network <nw-name>: rpc error: code = 7 desc = network <nw-name> not manually attachable.' when i try to create the container on the overlay network on swarm mode enabled, In docker 1.12 with swarm mode enabled, "Swarm" scoped networks (see the "SCOPE" column) cannot be used for docker run, only for services and now it has been rectified. I'm using updated version of docker, but still why i'm experiencing the error ? because the network just created but not manually attachable. To fix the issue we gonna use --attachable flag while creating network. [ --attachable             Enable manual container attachment ] (Need to create service on the overlay network, so that the overlay network will available / list on the worker node) docker inspect attnw (attnw is our test network)should show your own c

yum failed 6 times. Cannot continue!

Error while cPanel installation: (ERROR): - ssystem [EXIT_CODE] '/usr/bin/yum' exited with 1 (ignored) (DEBUG): - ssystem [END] (FATAL): yum failed 6 times. Cannot continue! fix: It looks like you have some name resolution issues on the server. Just run the following commands on your server and it will resolve the name resolution issues. #echo "nameserver 8.8.8.8" >> /etc/resolv.conf #echo "nameserver 8.8.4.4" >> /etc/resolv.conf if it is not working properly still facing same error, then here we go, # rpm -e --nodeps bind-chroot # rpm -e --nodeps bind # yum install bind

unexpectedly shrunk window (repaired) in dmesg log - TCP Peer

Don't Panic, This normally occurs when a client decides to reduce its TCP window size, without the server expecting it. This can be the case when fragmentation is an issue, or when the client is using an embedded device with very little NIC buffer memory. This is a completely normal behaviour, and you’re likely to see quite a few such packets in your log. The messages are informational only, and are used to debug networking issues. I’d be worried if you saw hundreds of thousands of these packets, since there are attacks that involve packet fragmentation and small window sizes, but otherwise it’s just the normal sort of noise you should expect to see on any internet-facing network. In fact, the “repaired” part of your message is showing that your network driver fixed the issue, which is usually done by concatenating the payloads of two fragmented packets together. Shouldn’t be an issue at all. … … … … … … … … … … … … … … … … … … … … … … … … … … … … … … …
