Re: [MooseFS-Users] Access to data while upgradeing from 1.6.27 to 2.xxx?

[Piotr R. K. <pio...@mo...>]

Hi Andreas,

yes,
you’ll be able to access your data with your 1.6.27-5 clients.

Please remember to do a backup of metadata, and please remember that
we recommend to do the upgrade in the following order:

1. MFS Master (needs to be done first of all)
2. MFS Metalogger
3. MFS Chunkservers
4. MFS Clients (Mounts)

Please also read this document before starting the upgrade:

In case of any questions, please don’t hesitate to contact us.



Best regards,
