we use evo ssd in large numbers and there is no specific speed problem with it. you just cannot use it in host with high io. I ve seen evos going to 99% wearout within 1 month under certain workloads (dbs mainly). others run for years without problems. and of course there are fast pieces around

one method: boot your host with clonezilla, clone to external drive, restore to new nvme. iirc cloezilla ask if you want to resize partitions to max (if not this can be done later)

even it's true technically speaking, I feel the urge to say that md-raid and ext4/xfs etc served very well and reliable over the last 20 years. the point is, that ceph and ZFS are everything else but slim. so we use depending on the usecase and available power/budget all of these technics. and...

_if_ you are going with NAS, I'd prefer a simple linux host with nfs and md raid. this way you have total control (eg can just take a disk and access data everywhere in case of failure, no prorietary controllers) and get more performance:price another advantage is simplicity which makes it...

Danke, hilft mir sogar sehr...

das ist nicht richtig. du brauchst nicht zwingend einen netzwerk storage für einen Cluster. manche dinge wie ha oder live Migration funktionieren dann nicht, aber einen custer hast du ja trotzdem.

wir haben das auch so gemacht um die Kapazitäten zu erhöhen.

die Frage würde ich gerne um Antivirus ergänzen. PMG unterstützt nach erster kurzer Recherche nur Avast. Deren Websites sind bzgl Linux Unterstützung aber nicht sonderlich vertrauenserweckend. Grund für die Frage ist die Erkennungsrate von clamav

one usecase: bonding is the way to get redundancy in production scenarios you would have your nics connected to different switches (within a stack) so parts can fail or reboot (e.g. for firmware upgrades) without interruption of services

for future forensic/recovery it is important, that you stop write access to the disks involved. so stop the storage or pve host. depending on your storagetype and filesystems there are different tools to recover deleted files. if the data is important you should consult professional...

remove all debian kernel there are dependencies (firmware iirc) that trigger the removal of pve

you can not imo. what are you trying to achieve by deleting?

you have to resize your vg, your lv and finally the filesystem. there are a lot of howtos about lvm on the net. search for resize lvm...

if you have a hw raid, use it. its not recommended as stated above. the official way to go with proxmox is zfs. one other possibility is mdraid I share the opinion of t. that hw raids are pain. with zfs and ceph you must not use it other than jbods/hba mode. and if course you can mix the...

I dont understand the question.... you have a raid system. so if a disk fails, you have to replace it of course.

md raid or software raid is a default ability of the debian installer

you can install debian with software raid and proxmox on top of it.

das würde ich jetzt nochmals nachlesen, aber so aus dem Gedächtnis setzt auch systemd-timesyncd aus Gründen die Zeit nicht hart in grossen Sprüngen. Der drift der erlaubt ist, ist sicher auch konfigurierbar. ohne Gewähr... ich würde mal nachlesen ob o.g Verhalten auch bei service restart...

ntp on (redundant, non virtualized) firewall. they sync to ntp pool. internal firewall only allowed ntp source
