"simply disconnecting" is not so simple if we want the cluster to remain online and operational in the intervening time... but anyway, in AIS a local drive is abstracted as "mountpath", and attaching/detaching mountpaths is fully supported:
$ ais storage mountpath --help
Thanks for that clarification. Can one configure ais such that the external hard drive is simply used as a mirror instead of deciding to place partial buckets on it?
Should that be done with an appropriate mirror
config or maybe with an additional target instance?
In AIS, all drives are equal and equally utilized, and so - No, you cannot have a given drive "used as a mirror instead of, etc." This sounds like a very special logistics you have... so maybe a separate AIS cluster can help and a copy (ais cp
) in-between, not sure.
I have a use case where aistore acts as a storage backend for an air-gapped system. One requirement is to
walk the hard drive
to transfer data from the air-gapped location to some other place.I was wondering if there is a sane way to support simply disconnecting a hard drive and moving it to another location, reading data from it without the use of aistore and moving it back to the air-gapped ais instance?
The main blocker right now is this issue: https://github.com/NVIDIA/aistore/issues/140 If I simply plug out the hard drive, plug it back in and restart ais I see that issue. I'm wondering if there is a way to recover from that. (But let's keep that discussion in 140)
