Re: [OpenAFS] automatic replication of ro volumes
Cron has no more knowledge about when the r/w volume is in a consistent state than does AFS. Only the person(s) who make the changes to the r/w volume know when it's ready to release.

Re: [OpenAFS] automatic replication of ro volumes
Hi Jeffrey, it is common an openafs admin has to sync an ro volume after something is added to rw volume. This is done by the vos release command. I think its the only way. Are there automatic sync functions in the vol / fs server. The risk of automated volume releases is that the automated system does not know when the volume contents are in a consistent and quiescent state. ok, but vos release "knows" them ? Is there something against a crontab script as root with vos lock and vos release to all volumes (with an ro site) ? Sites often use remctl to grant end users the ability to release their own volumes. Automated releases of RO volumes are a poor substitute for replicated RW volumes. RW replication is a feature which was never completed for OpenAFS.

The risk of automated volume releases is that the automated system does not know when the volume contents are in a consistent and quiescent state. Sites often use remctl to grant end users the ability to release their own volumes. Automated releases of RO volumes are a poor substitute for replicated RW volumes.

[OpenAFS] automatic replication of ro volumes
Hi, it is common an openafs admin has to sync an ro volume after something is added to rw volume. This is done by the vos release command. I think its the only way. Are there automatic sync functions in the vol / fs server. Andreas ___ OpenAFS-info mailing list OpenAFS-info@openafs.org https://lists.openafs.org/mailman/listinfo/openafs-info
