Re: [Moosefs-users] problem metadata

[Michał B. <mic...@ge...>]

Yes, that's right you should use .tmp file. You can use this command:

mfsmetarestore -m metadata.mfs.back.tmp -o metadata.mfs changelog.1.mfs
changelog.0.mfs

All the data continuously generated in your IT infrastructure contains a
definitive record of customers, application performance, security threats,
fraudulent activity, and more. Splunk takes this data and makes sense of it.
