[Moosefs-users] We need your help! Mastertools brainstorming

[Michal B. <mic...@ge...>]

Hi!

 

You often ask "how to do this" / "why can't I do this in command line" and
every time we answer that sometime we'll prepare a set of tools called
"mastertools" where you could do lots of useful tasks. And this moment is
slowly coming up :)

 

We have thought of some tools but for sure you can give us more suggestions:

 

- mfschunkinfo chunkid [, chunkid ...]

- mfsinodeinfo inode [, inode ...]

- mfsinfo or mfsstats (?) - returning how many files, folders, missing
chunks, etc. there are 

- mfscsinfo - returning list of connected chunkservers

- mfsmlinfo - returning list of connected metaloggerów

- mfsclinfo - returning list of connected clients

- mfshdinfo - returning list of connected hard drives

 

Do you think of any other useful tools which could be indluded in the
"mastertools" set? Please share your thoughts with us.

 

Thanks!

 

 

Best regards

i found back that you asked about new command line that would be useful :

1/ a way to know to wich file belong one chunk.
i had a broken server that gave me many bad crc. and i had to wait  the 
log tell me which file was broken with a bad crc chunk.

2/ a way to re verify a crc on a chunk, or to force the check of all the 
chunks on a chunkserver.
as for now, i changed my server, i would like to know in which state are 
the chunks on my hard-drives...

thanks for all your great job on moosefs

A (maybe) weird idea:

mfsmlinfo --fullstate : Analize and report state, age and useability of metadata on any metalogger connected (very useful just until a redundant master won't be available)

mfsmlpromote - promote av metalogger to metaserver
mfsmqstatus  - shows a metaserver and loggers as a quorum and it's
                status
mfsmsreelect - reelect metaserver (between metaserver and loggers)

I know its new functionality, especially for HA around metaserver, but 
it is extremely important.

* mfs(repair,erase,delete ...) (chunk or inode number) (/mount/point) ,
on any location (trash or cluster, .....) force ....

* mfscsinfo, mfsmlinfo, mfsclinfo, mfshdinfo
standardized outputs for alerting purposes (read_error, write_error,

* massive operations with find, ls (mfsfileinfo, .....
