Re: [MooseFS-Users] Chunkserver failed to start after reinstallation

[Aleksander W. <ale...@mo...>]

Hi,

If you have reinstalled chunkserver you probably removed
/var/lib/mfs/chunkserverid.mfs file with chunkserver metadata ID.
Now chunkserver and chunkserver disks are in mismatch condition.

Solution is simple but very dangerous.
*Please understand - this is security solution to prevent connecting
chunkserver to wrong master!!!*
If you have 100% sure that this disks will be connected to right master
and there is no possibility that there is some mistake in configuration
please remove .metaid file from /mnt/sdb and /mnt/sdc folder.

If you connect chunks to wrong master they will be removed.
