| Description |
|
Currently mongod --repair rebuilds indexes in the dbpath/_tmp directory. If a deployment is low on disk space, this can easily cause out of disk space errors and halt the repair. If a user specifies --repairPath, use --repairPath location to build indexes. Current workaround is to symlink the dbpath/_tmp directory to a volume with more free space. |

Should this improvement instead be the ability to specify the temp path explicitly? I think that is the direction we are going in anyway, for the server and all the tools as well. |
