[lustre-discuss] Can we re-index the lustre-discuss archive DB?

[Cameron Harr]

To the person with the power,

I've been trying to search the lustre-discuss 
(http://lists.lustre.org/pipermail/lustre-discuss-lustre.org/) archives 
but it seems only old (<= 2013 perhaps) messages are searchable with the 
"Search" box. Is it possible to re-index the searchable DB to include 
recent/current messages?


Thanks,

Cameron

Re: [lustre-discuss] Is there aceiling of lustre filesystem a client can mount

[肖正刚]

  Hi, Jongwoo &  Andreas

Sorry for the ambiguous description.
What I want to know is the number of lustre filesystems that a client can
mount on the same time.

Thanks

Depending on what limits you are looking for, you may find this link useful:

https://build.whamcloud.com/job/lustre-manual//lastSuccessfulBuild/artifact/lustre_manual.xhtml#settinguplustresystem.tab2

For capacity and performance, the upper limits are probably "higher than what 
you have money for". :-)

Cheers, Andreas

Re: [lustre-discuss] Is there aceiling of lustre filesystem a client can mount

[Jongwoo Han]

I think your question is ambiguous.

What ceiling do you mean? Total storage capacity? number of disks? number
of clients? number of filesystems?

Please be more clear about it.

Regards,
Jongwoo Han
