IIsThisThingOn reacted to Falk R.'s post in the thread Garbage collection blockiert wegen vollem ZFS storage with
Like.
Am besten immer mit Quota arbeiten. Der GC kann nicht laufen, da ZFS zum löschen auch Metadaten schreiben muss, braucht man selbst zum löschen erst einmal ein wenig Platz. Falls das trotzdem noch einmal passiert gibt es eine einfach Lösung... -
IIsThisThingOn reacted to Johannes S's post in the thread Bcachefs storage plugin for Proxmox VE with Like.
Isn't bcachefs still developed outside the kernel due to it's maintainers inability to cooperate with other people by following the kernel developers processes? Then I will pass

IIsThisThingOn replied to the thread Empfehlung für einen Neuling - Sicherung ein ca. 20 TB VM eines PVE auf einem PBS und anschließend auf Band.Ich würde auch kein stinkendes Windows laufen lassen, wenn nicht unbedingt nötig ;) Aber ja, ich lasse auch ca. 10 Windows VMs mit 100GB laufen. Aber die sind auch nur einmal (nach Erstellung) gesichert, weil die keine schützenswerte Daten...

IIsThisThingOn reacted to TErxleben's post in the thread Empfehlung für einen Neuling - Sicherung ein ca. 20 TB VM eines PVE auf einem PBS und anschließend auf Band with Like.
Zaubern kann da keiner. 20TB sind schon ein Klops. Selbst reines rsync muss die Datenmenge duchflöhen. Von verify/garbage auf lahmen HDDs will ich gar nicht sprechen.

IIsThisThingOn reacted to Neobin's post in the thread set vm ram in GB instead of MB in gui with Like.
Of course, and I would even say obviously (but seems not so), it is not about replacing the MiB option with GiB, but having a GiB option additionally...

IIsThisThingOn replied to the thread Empfehlung für einen Neuling - Sicherung ein ca. 20 TB VM eines PVE auf einem PBS und anschließend auf Band.Proxmox VMs sind blockstorage. PBS sichert nicht mit ZFS, sondern mit eigenen Chunks. Das ist architekturbedingt langsam. Wenn du es also einfach haben willst: - Halte die VMs klein. 32GB sollte mehr als genug sein. Dann geht auch der Backup...

IIsThisThingOn replied to the thread set vm ram in GB instead of MB in gui.why not go the PHP/Docker way? By allowing to insert either 128M or 16G, both groups are happy.

IIsThisThingOn reacted to fabian's post in the thread PBS incremental backup scans 162 GiB immediately after full 298 GiB backup finished with Like.
1: because the answer to 3 is yes, the bitmap tracks dirty writes since the start of the backup, since the backup itself is based on that point in time (it uses copy-before-write filtering, so that data being overwritten is backed-up before it is...

IIsThisThingOn replied to the thread set vm ram in GB instead of MB in gui.Should have been more precise. I think it should be done like php.ini settings (and many other software) uses these settings. 344M 5G 1T Right know, I have to calculate "hmm... 1GB is 1024MB. So that means * 2 * 2 = 4096 gives me a 4GB machine...

IIsThisThingOn replied to the thread set vm ram in GB instead of MB in gui.No, but I would expect that instead of the fixed MB, I can insert either 512M or 4G or 1T. Just like with PHP and many other software.

IIsThisThingOn reacted to Mike_Scholes's post in the thread ZFS raidz1 and snapshots, again with Like.
We have PBS for local backup of our HA cluster, various proxmox servers around the server room and our build proxmox servers. They have various schedules and retention times dependent on data and all encrypted of course. Then we have an air...

IIsThisThingOn replied to the thread ZFS raidz1 and snapshots, again.Maybe you are using SSDs or only 1TB drives with a low resilver time. IMHO even then RAIDZ1 is not really save. Imagine if one disk fails, and you switch out the wrong disk. ZFS has almost no guardrails and will let you do many stupid things...
-
IIsThisThingOn replied to the thread ZFS raidz1 and snapshots, again.For your information, your 4 wide RAIDZ1 offers 66.66% storage efficiency, while being very insecure. That is not that much better than a way better performing mirror at 50%. You won't see this problem directly in ZFS. You will notice that...
-
IIsThisThingOn replied to the thread ZFS raidz1 and snapshots, again.I know it is pedantic, but in this specific case, there is no padding :) He/she is wasting storage because of pool geomerty. With 4 drives, we get a stripe 4 drives wide. Each stripe has three 4k data sectors (12k) and one 4k parity sector. For...
-
ILots do. I also always have to suggest this as well. If it were such a bad idea local-zfs wouldn't use it. I made a ticket in argument of changing the default if you care. I have a little snippet here which might be useful if you still need to...
-
II agree. First performance and iops will suffer compared to a mirror or striped setup, second it will lead to waste due to padding see: https://forum.proxmox.com/threads/fabu-can-i-use-zfs-raidz-for-my-vms.159923/ Another issue are the large...
-
ITherefore I did not specify the disk. If you do, you need -r as option So you missed checking the thin provision box in your storage configuration in the PVE UI:
-
IIsThisThingOn replied to the thread ZFS raidz1 and snapshots, again.before we dive too deep into snapshots and their storage consumption, we should IMHO look first at two more important issues. I would argue that running RAIDZ1 is unsafe. Dell marked RAID5 to be against best practice and unsafe something around...

IIsThisThingOn reacted to _gabriel's post in the thread Guest agent not running on Windows 11 with Like.
if you read the topic, and if you have same problème, then fleecing greatly help. But as we have not info about your case, nobody can guess. Open new topic is better with your specs and your flow

IIsThisThingOn replied to the thread Guest agent not running on Windows 11.using a HDD for fleecing solved it for me
