On one of the CentOS Linux release 7.6.1810 (Core) server the mac address's of networfaces got changed e.g. eth0 has eth3's mac address and so on . Does anyone know why this happens and how to resolve it ?
After reboot of CentOS Linux release 7.7.1908 (Core)server ,it stopped xfs support and throws below error
mount: unknown filesystem type 'xfs'
#lsmod | grep xfs
is not showing anything and #modprobe xfs is also not working .
#find /usr/lib/modules/$(uname -r) -name *xfs*

I want to use linux based NFS datatstore in vmware esxi 6.5 .Which linux file system is best suited for this prurpose ? I tried xfs,but it has defrangementation issue mentioned here https://blog.codecentric.de/en/2017/04/xfs-possible-memory-allocation-deadlock-kmem_alloc/.
I am using pfsense 2.2.6-RELEASE. My configuration is as follows:
- Two static WAN, One LAN
- Using google and opendns
- Configured WAN-Load balancing and WAN-Fail-over
- Using aliases in firewall rules
When the primary WAN interface goes down, the DNS stops working.
There is fix available on pf-sense forum, but the forum is closed. The link for forum posts is here https://forum.pfsense.org/index.php?topic=43982.0
