The "short" option is still pretty long! We're just looking for the ANSWER section:

Maximum Open Files on Ubuntu, Mac OS, ChromeOS
We've had a report with uploading large numbers of files using
ipfs-deploy with Fission support that you may need to increase the number of open files that your operating system supports. This could also occur with fission watch.1
sudo launchctl limit maxfiles 65536 200000
Copied!
As described in the article, you'll want to add it to your bash or other shell profile so this change is permanent.
On a Chromebook in the native ChromeOS shell? Yeah, Boris hit this issue too when running large jekyll or gatsby builds:
1
sudo sysctl fs.inotify.max_user_watches=1048576

Re-installing brew on Mac
We've had some hiccups with our brew formula recently. To re-install / reset brew, run the following:
1
brew untap fission-suite/fission
Copied!
1
brew tap fission-suite/fission
2
brew install fission-cli

DEBUG mode for fission cli
If you want to see what the Fission CLI is doing under the covers, you can turn on DEBUG mode by calling commands like this:
1
DEBUG=true fission up .
Copied!
You'll see that
fission up calls your locally installed ipfs command to add files to IPFS. We can see that it's using the 0.4.22 version of ipfs, installed using Homebrew in the "Cellar" where brew keeps installed items.
Then, it sends the hash of the entire directory to our web API, which pins it and fetches the files directly from your laptop and any other IPFS nodes that already have copies of those files in the network.
In this case, we can see that after the "Remote pinning Qm…", there is a 504 Gateway Time-out error from our server. This is a known issue, which we're working on to support large files / large quantities of files.
The
--verbose flag can be run on most commands these days. See the CLI docs for working with apps for more info.Ports for Managed Fission IPFS Node
The fission CLI installs a managed IPFS node. It runs on port
10235.
