https://www.cyberciti.biz/faq/apt-get-hold-back-packages-command/ but.... why? just update all your nodes.

I dont know if its any different then the intel download link, but I did get this nic to work with pve8.2. I used this src: https://github.com/intel/ethernet-linux-ixgbe/releases and before you ask, it was a customers install and I no longer have access to it ;)

quts 5.2 uses the scst target. It should be relatively easy to write the plugin to facilitate zfs-over-iscsi. I'll look for documentation for user provided plugins- maybe I'll write it.

defaults { verbosity 1 path_grouping_policy multibus find_multipaths smart } blacklist { devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*" devnode "^hd[a-z]" property "ID_ATA" } I dont understand how this is related to...

in a container there is practically no difference. debian tends to be a little lighter but not significantly so.

just spitballing here, but have you tried the manual? https://h10032.www1.hp.com/ctg/Manual/c00814876.pdf but seriously, default multipath.conf should work just fine. I have a corevault (same controller tech) and I didnt have to do any customization.

so the question is, did the fencing notifications occur before or after the node rebooted? describe your networking setup.

do you have the watchdog enabled? --edit of course you do. check pve logs for fencing notifications.

That is really not a true statement. All you need to do is recreate the datastore, and make a new vmid.conf- it doesnt even matter if you knew that the original settings were; all the important stuff is in the guest os anyway. the qcow filename would be in the form of "vm-vmid-disk-n". all you...

those other two bits of info are important.

the consequences of this arent really impacted by the TYPE of cpu you use. AMD and intel are both fine for ceph. Many variables aside of number of vms. how many nodes, OSDs, etc. I... dont think you and your dell rep were speaking the same language. that, or he doesnt know anything about ceph...

whats the content of: hostname your hosts file /etc/network/interfaces

This is a recipe for disaster on DHCP outage. set your ips people.

It depends on your role. IF you are in a position of responsibility, you explain to your client that their server control interface should not be exposed to the internet. full stop. if you dont know why, you should probably not accept a position of responsibility. If the client doesn't care-...

you also need to have at least 2 mds daemons ;)

what.... failover? I guess I missed this part of your question. ceph is multiheaded; as long as you dont have a service with only one daemon, there should be no "failover" to speak of. If you only have one active mds daemon, there will naturally be a "failover" period to a standby; the amount...

3 node config is an absolute minimum configuration for ceph. I dont consider 3 node to be either good for production or good for a predictor of proper performance simulation. on top of that, 2 OSDs per node is way too little. there is no granularity for io which means all your IOs vye for the...

This isnt an "issue" as such. You have more pgs then your system can scrub within the defined timeframe values. There are a number of knobs for you to turn, including: - increase the time required (osd_deep_scrub_interval, osd_scrub_interval_randomize_ratio) - increase your scrub load...
