reboot when installing centos 7 with mdadm ?

Hi,

if i have 8 SATA3 SSD, for shared hosting,
i want to run cloudlinux and cpanel on it.

compare hardware raid card with mdadm raid10,
do you recommend which one ?

i make searching,

1. some people say raid card will be quicker,
but cpu are quick now,does it really have the difference ?

2. some people say raid card has battery and mdadm only server power,
when server's power fail,
mdadm's raid data may break,is it real ?

Hi,

with samsung's SSD,
both 860 PRO 512G and 870 EVO 1TB have the same 600TBW and 5-years warranty.

i want to use the SSD for centos's boot and MySQL with mdadm raid1,
which one would you recommend ?

Hi,

With your experience,

1. For hosting sites(such as WordPress),
Will nvme ssd be much quicker than sata ssd ?

2. Will ssd with hardware raid card be much quicker than mdadm software raid ?

I just setup a server 2 x 500GB SSD - CentOS 7.9 - cPanel 94.0.2, and the filesystem will not allow quota function because the default is quotas disabled.

I ran the cPanel tool to enable quotas and it returns true with notice to reboot, but it remains disabled

Code:

journaled quota support: kernel supports, user space tools supports (available)
UUID=627a44c8-1c7b-4a4f-8236-3b83f82300a5 (already configured quotas = 1).
UUID=7bd01ba6-af01-423f-986a-84a588c2a404 (already configured quotas = 0).
Updating Quota Files..........Done
Quotas have been enabled and updated.

You must reboot the server to enable XFS® filesystem quotas.

Has anyone had this issue and did you resolve it? If yes, what was the method?

Hello,

So with the recent announcement of CentOS coming to and end i find myself wondering which is the best option for a new Dedicated server.

Do I still go with CentOS 7 or is there an alternative option now?

I know that CentOS is only EOL in 2024 and CentOS 8 is EOL now in this year 2021. So it makes very little sense to go with CentOS 8.

Any opinions welcome

Anyone else get a server powercycled at reliable site on 1st Jan ? Happened at 6:23pm central time on 1/1

They are claiming its the OS or BIOS but I've shown them via event log that windows update is off and that there was no user or software initiated reboot

Thanks

I rented a dedicated server about 6 months ago and at the beginning it wasn't really any issues.
Heres the downtime report https://i.imgur.com/mE5V2eJ.png

At the beginning i encountered few downtimes but that was due their network being compromised and it can happend sometimes and the owner promise they will upgrade their infrastructure to fix this issue.
After few months after, my server lost power and rebooted. The owner replied back that they will fix this issue but the same issue occured again however their provided reason at that time was because their UPS malfunctioned.
Few more downtimes after that incident, they said, fire department told them to shutdown their power, while their electricity provider had an occuring issues beyond their help. Excuses keep piling on and its almost as if they dont even have UPS.

Last year october and november my server started to randomely reboot with seemlingly no explanation. I hired sysadmin and they couldnt find an issue. They suggested this could be a hardware issue. Due to the hardware parts it would take provider months before the provider can replace all the hardwares so i had to wait.
And waiting i did, and until when the day finally arrived. From all my exchanges with this company, ive only talked with the actual owner. This seems to be really a one man show. Worst is that this owner is incompetent.


So we went through with the server swap, changing ssd to the new server hardware. However issue occured with the new hardware enviroment not recognizing my ssd partitions. Sysadmin couldnt do much in rescue mode as they cant gain the error logs which dracut provided in the failure mode.
The issue is that the dracut log is generated in a volatile disk path so ifwe rebooted the logs would be gone.

The owner had significant issues where the server didnt recognize the flash drives so we couldnt export the logs.
This was a 24 hours conversation exchange. We litterally end up googling. Even the owner was googling and asking if a centos forum post could be the solution.

I asked if they can setup a KVM so my sysadmin can access the dracut logs.
24 hours after, the owner still has problem setting up kvm.
That was my last patience with this provider. I told him to change back to the old server hardware and the server was online again. I ordered a new server from a different provider(reliablehostingservices.net) and did rsync and terminated my server with dedioutlet.

The sheer amount of incompetence is just baffling. Owner googling for solution, trying to ask his "developer" on how to fix kvm setup to no avail.

Hi all,

Sorry if I posted this in the wrong forum; had trouble deciding whether to put it here or in the VPS forum.

I am running to some trouble with trying to properly expose a particular CPU topology to a VPS on a CentOS 8 server running KVM and Virtualizor, and was hoping you might be able to help. Not sure if I am doing something wrong and/or not understanding something.

I have an AMD Ryzen 5600X dedicated server with 6 cores and 12 threads. I created a VPS to which I am trying to assign 8 VCPUs (4 cores with 2 threads per core for a total of 8 threads). In Virtualizor, I set CPU units to 1000, CPU cores to 8, and CPU percent to 800. I then select the CPU topology option and specify 1 for sockets, 4 for cores and 2 for threads. CPU mode is host-passthrough. However, when using the lscpu command within the VPS or when checking /proc/cpuinfo, the topology shows up as 1 socket, 8 cores and only 1 thread per core. Does anyone know why this is? Would this affect performance within the VPS at all (that is, are applications not able to take advantage of hyperthreading, or does it even matter that the topology shows up this way)? The topology shows up as expected on an Intel E-2136 server that I tested on, so not sure what the difference is here.

Thanks for any tips you can provide!

This is my first post on Web Hosting Talk Forum. I need your help. My server consists of 2 hard drives. 1TB x 2 SATA. In last week my server gets slow down and the data center noticed that I have an issue with my hard drive. They said " We are showing drive SDB is failing and will need to be replaced, " They asked me to take a backup and replace the hard drive immediately.

I have 2 hard drives and I have installed CentOS 7 with software RAID 1 ( Software RAID ). So now my question is do I need to restore the backup once we replace the hard drive. ? or is it syncing with RAID without any manual backup restoration ?
