Hi LnxBil, thank you for this added detail. I just did some digging/reading online, so far the most-clear thing I could find to talk about HugePage and possible impact on KSM was here > here in redhat docs
If I am reading it correctly, HugePage enabled will likely give better performance to...
Hi everyone, thank you for all the great replies. I must admit I had forgotten about the obvious baseline problem of "what if ram is heavily sliced up" - this was definitely a factor here, ie,
server was online for ~90 days
initially all VM were spun up, with less than 64gb allocated to my...
Hi, I wonder if someone can help me understand maybe this situation. I've got a proxmox node with a pretty classic config, ie,
OVH hardware hosting environment, MD Raid storage, 2 x 4Tb mirror NVME_SSD as my primary proxmox datastore
Host is a 6-core Xeon 12 thread, with 128gb physical ram
Yes, they are visible as shown / as per usual / once the VM was restarted. So. This is great to know though that doing a disk move will effectively give me clean slate new instance disk / and should banish them. I am pretty sure I've got enough space on the local SSD proxmox storage pool to...
slow footnote on this thread. I gave this a go this morning, and it did not quite go as expected. I think this means I just have to ignore it and not worry, but just in case of interest.
I tried to follow hint to remove snaps, after power down the VM
command line it tells me "no"
Thank you very much for the reply / this information! Greatly appreciated.
Part of the drama around this whole thing, was that the first-pass test snap/remove was done smoothly on Friday
and it seemed to go ok
but when the NFS server had the added background performance issue of raid metadata...
I am not super familiar with how this is implemented and meant to work, and I can't find any hints when search forum, so I wanted to briefly ask if anyone can comment.
This is on a proxmox latest 8.0.4 host
VM is using qcow2 disk format
qcow2 is stored on a Proxmox VM storage pool - local...
Hi, just quick update on this thread. I did a bit more work. I managed to get remote DRAC access to console on this server working and this makes it a lot easier to move this along.
Tried one hint based on discussion-post here...
Hi donhwyo, thank you for this reply. Very much appreciated. Good to hear the h200 works for someone as intended!
I know firmware version is displayed at boot-time but that is a pain if you don't intend to reboot anytime soon. It is part of the messaging that goes by, ie, Dell Logo > CPU...
Hi, thanks for the added thread content.
I just double checked to confirm,
Dell Perc H700 is an LSI 2108 chipset
as per Dell tech ref > https://i.dell.com/sites/csdocuments/Shared-Content_data-Sheets_Documents/en/perc-technical-guidebook.pdf
Dell Perc h200 is based on LSISAS2008/62114B1 I...
..yes..., I tried a few different installer scenarios and they had same core problem it seemed, ie,
-Debian.9 minimal net install media
-proxmox.4 based on debian8
and I could not get it to detect the disk.
-then boot with my 10year old sysrescue"cd" USB key and it was...
Thank you for the reply.
> I realize the UBSAN is a warn now. ie, bit of a red herring I should ignore.
> I have already updated the system as follows
(a) new / latest BIOS for mainboard in the dell r815
(b) raid card (perc 700) was on latest firmware from Dell, I had problem...
Hi everyone, I am trying to debug a problem and hoping for a gentle kick in correct direction
I'm trying to figure out if there is a pre-cooked proxmox installer ISO that can be downloaded
which has "Edge Proxmox Kernel" present in the installer media
I ask because
- I've got a dell r815
just pinging this thread to ask status (2 weeks later I think approx?)
I am asking because I'm trying to sort out a new-install proxmox-latest on a Dell R815 with a PERC h700 which also uses mpt3sas driver and I cannot get proxmox to work with the device. Even with addition of kernel boot...
Ping? does anyone have any thoughts comments? I am still baffled why MPT_SAS is so busted on this hardware with more recent linux/proxmox; but it works fine with an ancient Sysrescue/10year old boot media. Thank you. (!!)
A footnote on this thread in case it helps others. I came here via google search quite a while after this was an active thread but still seems relevant.
I've got a fairly current (Proxmox 7.4) cluster setup of a few nodes. And I've noted that LXC Containers - if I migrate from one node to...
Hi, here are some photo snips of dmesg / errors from various attempts, with brief text to try to help give context and clarify.
these are all with h700 card, and a pair of 1Tb SSD attached with a single raid mirror volume defined.
First error ref from Proxmox-latest installer
key text error...
Thank you. That is a good suggestion. I agree, my feeling that MPT SAS was expected for me to be "a no brainer, easy good reliable because super standard and extremely well supported". Hence all my frustration with this.
With my test work yesterday - On new-current Debian and Proxmox, there is...
A small followup on this. I banged my head on this problem again today. I thought I was being clever, I got my hands on a nicer H700 raid card which is better version of the h200. I foolishly assumed that the better HW Raid features of the h700 might make it work better.
Alas I have the same...
