Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

Please wrap all code, files, input & output/errors in CODE tags.
It makes it easier to read and preserves multiple spaces for indenting or fixed-width data.

Further to what my learned friend Gull04 has written, you have failure on eth4 too, so the IP will have moved back to eth0 again.



I hope that this helps,

Now active in eth0. eth4 not active. why eth4 still receive package but no transmission package from eth4.
Code:

Hi Samran,

This seems to be standard traffic on the bonded interfaces, here I have a bond (bond0) comprising eno1 and ens2f1. As you can see the secondary interface has some Recieved Packets, probably just the bond checking that it's active.

Code:
xI/F Name Recv=KB/s Trans=KB/s packin packout insize outsize Peak->Recv Trans
x    eno1      1.9       0.5      13.5    2.5   145.7  201.2        3.7     15.9
x    eno2      0.0       0.0       0.0    0.0     0.0    0.0        0.0      0.0
x    eno3      0.0       0.0       0.0    0.0     0.0    0.0        0.0      0.0
x    eno4      0.0       0.0       0.0    0.0     0.0    0.0        0.0      0.0
x   bond0      1.9       0.5      13.5    2.5   145.7  201.2        3.7     15.9
x      lo      5.6       5.6      21.0   21.0   274.9  274.9       53.3     53.3
x  ens2f0      0.0       0.0       0.0    0.0     0.0    0.0        0.0      0.0
x  ens2f1      0.7       0.0       5.0    0.0   136.7    0.0        2.3      0.0

If you need further validation on your server, then I'd suggest that you would maybe want to run;

Code:
># tcpdump -i eth4

Please note depending on network traffic you will probably see significant output.

Regards
