Re: [PLUG] Is it possible to move data from a SAS drive to the newly installed SSD?

Eric,

Sounds like an idea. Would need to do a deep dive again -am a little rusty on everything - especially new stuff added to core like taproot.

Email me outside this chain and we can talk. I prob need to create a full node again since I got lazy when my previous crapped out and got busy at work.

This is an interesting aside but I'll put it here for all... Today I found out a new thing with CashApp by Jack (twitter). I'm changing banks and wanted to load some on that while I do all the money moving and found out you can load some cash on the credit card connected to the app AND add a boost which is sort of like cash back cards. The difference is they give you bitcoin. For a $14 pizza got $0.80 in bitcoin added to my account. For those with Bitcoin FOMO, seems a no effort way to own some Bitcoin with little effort. Venmo might be the more popular one out there, but there is a lot more functionality with CashApp and being able to choose different boosts (I mentioned one out of many).

Joe,

Reminding Humera, you presented at Humera's meet-up group, Exton blockchain meet-up a couple years ago she had a bunch of IT related questions way outside my area of expertise, so I referred her to PLUG.

Perhaps in the near future we can do a cros-over preso on IT requirements for crypto / mining.

Regards,
Eric

Not sure how much has changed, but a 2018 article by Jameson Lopp said, and I quote:

"Running an archival Ethereum node requires a ton of disk I/O since you’re executing every smart contract ever performed in the history of Ethereum and updating the state on disk. It’s common knowledge now that if you try to sync an archival node on a machine with spinning disk drives, it will never catch up to the tip of the blockchain — there simply aren’t enough IOPs available. Thus, you MUST have a solid state disk to run an Ethereum node."

Yes, it's possible, if you can have both PERCs installed at the same time. If they're PCIe models, you're fine, if they're the proprietary Dell semi-integrated modules, you'd need to remove the one to install the other.

Hi,

I have my Dell R510 server configured with raid 6. It has been downloading Eth1 (Geth) chain for last 4 days and it’s not even half way done.

I am finding out now that even if the chain is fully downloaded and synced, I will have issues with the SAS drives because they’re too slow for this purpose.

I am thinking about upgrading the perc card to the 8700 and upgrading a few drives.

Would it be possible for me to move the already downloaded data to the new drives or would I have to download everything all over again?

Thanks
