Version information:

go-ipfs version: 0.4.17-
Repo version: 7
System version: arm/linux
Golang version: go1.10.3

Type: Bug

Description:

When trying to use the badgerds profile on an odroid xu4 with a btrfs home dir, I get the following output:

initializing IPFS node at /ipfs/debugbadgerds
generating 2048-bit RSA keypair...done
peer identity: QmbuM7F8j8rVrQtFVgTqQEmp1nHzYqXpj1kngY8CaLY672
Error: Unable to mmap RDWR log file: invalid argument

Hopefully relevant strace is attached.

Hey @jcaesar, Badger is trying to mmap twice the (default) size of the log file, i.e., 2 GB, from the specs I'm seeing of the ODROID-XU4 that's all the memory available to the embedded device, could you try reducing the value log file size in the go-ipfs config file?

(BTW, this is a great deployment test, I'd love to see how it progresses :))

Sorry, I should have clarified that the option is vlogFileSize (the document I pointed to didn't have that information), e.g.,

  "Datastore": {
    "StorageMax": "10GB",
    "StorageGCWatermark": 90,
    "GCPeriod": "1h",
    "Spec": {
      "child": {
        "path": "badgerds",
        "syncWrites": true,
        "vlogFileSize": "100 M",   <---   (In quotes, between 1MB and 2GB.)
        "type": "badgerds"

(Is this information available in any document?)

It should be here, but is not: https://github.com/ipfs/go-ipfs/blob/master/docs/datastores.md#badgerds

@schomatis Reducing the vlogFileSize indeed does get rid of the problem. The limit seems to be 1073M.

I'm wondering why this problem doesn't occur on some of my x86_64 VPSs with less RAM…

I really have no idea, but I'm suspecting the 32-bit nature of the Cortex processors might be a problem, 2GB is just over the top of the maximum positive signed integer (which would explain the EINVAL being returned instead of ENOMEM).

There seems to be an issue in Badger about it: dgraph-io/badger#514.
