* geo-rep-cli: added a new option "no-verify" to geo-rep create.darshan n2015-03-121-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new option called as "no-verify" to geo-rep create command. With no-verify option, following checks does not take place before session creation: * if ssh port 22 is open in slave * has proper passwordless ssh login setup * slave volume is created and is empty * if slave has enough memory This option is needed by ovirt-engine as the tasks done by push-pem is taken care by ovirt-engine and also the above checks are done. Thus creation of password-less ssh can be avoided when geo-replication is managed through ovirt. Usage: volume geo-replication [<VOLNAME>] [<SLAVE-URL>] { create [[no-verify]|[push-pem]] [force]| start [force]|stop [force]|pause [force]| resume [force]|config|status [detail]| delete } [options...] Change-Id: I975265f27d6434be5409438257d09cd4190c9159 BUG: 1198615 Signed-off-by: darshan n <dnarayan@redhat.com> Reviewed-on: http://review.gluster.org/9799 Reviewed-by: Aravinda VK <avishwan@redhat.com> Reviewed-by: Kotresh HR <khiremat@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Krishnan Parthasarathi <kparthas@redhat.com> Tested-by: Krishnan Parthasarathi <kparthas@redhat.com>

* glusterd: Move brick order check from cli to glusterd.ggarg2014-09-241-4/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | Previously the brick order check for replicate volumes on volume create and add-brick was done by the cli. This check would fail when a hostname wasn't resolvable and would question the user if it was ok to continue. If the user continued, glusterd would fail the command again as the hostname wouldn't be resolvable. This was unnecessary. This change, moves the check from cli into glusterd. The check is now performed during staging of volume create after the bricks have been resolved. This prevents the above condition from occurring. As a result of this change, the user will no longer be questioned and given an option to continue the operation when a bad brick order is given or the brick order check fails. In such a case, the user can use 'force' to bypass the check and allow the command to succeed.

| | | | | | | | | | | | | | | * As of now snapview-server is polling (sending rpc requests to glusterd) to get the latest list of snapshots at some regular time intervals (non configurable).

* posix: add a simple health-checkerNiels de Vos2013-07-031-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Goal of this health-checker is to detect fatal issues of the underlying storage that is used for exporting a brick. The current implementation requires the filesystem to detect the storage error, after which it will notify the parent xlators and exit the glusterfsd (brick) process to prevent further troubles. The interval the health-check runs can be configured per volume with the storage.health-check-interval option. The default interval is 30 seconds. It is not trivial to write an automated test-case with the current prove-framework. These are the manual steps that can be done to verify the functionality: - setup a Logical Volume (/dev/bz970960/xfs) and format is as XFS for brick usage - create a volume with the one brick # gluster volume create failing_xfs glufs1:/bricks/failing_xfs/data # gluster volume start failing_xfs - mount the volume and verify the functionality - make the storage fail (use device-mapper, or pull disks) # dmsetup table .. bz970960-xfs: 0 196608 linear 7:0 2048 # echo 0 196608 error > dmsetup-error-target # dmsetup load bz970960-xfs dmsetup-error-target # dmsetup resume bz970960-xfs # dmsetup table ... bz970960-xfs: 0 196608 error - notice the errors caught by syslog: Jun 24 11:31:49 vm130-32 kernel: XFS (dm-2): metadata I/O error: block 0x0 ("xfs_buf_iodone_callbacks") error 5 buf count 512 Jun 24 11:31:49 vm130-32 kernel: XFS (dm-2): I/O Error Detected.

* doc: Move admin-guide to markdown format.Vijay Bellur2013-06-2522-0/+6345
| | | | | | | | | | | | | | | | | | | | | | | | | | Editing markdown is probably more easier than xml. pandoc can then be used for conversion to html, pdf and any other necessary formats. Note that pandoc has the following input and output formats: Input: markdown and (subsets of) Textile, reStructuredText, HTML, LaTeX, and DocBook XML. Output:plain text, markdown, reStructuredText, XHTML, HTML 5, LaTeX (including beamer slide shows), ConTeXt, RTF, DocBook XML, OpenDocument XML, ODT, Word docx, GNU Texinfo, MediaWiki markup, EPUB, Textile, groff man pages, Emacs Org-Mode, AsciiDoc, and Slidy, Slideous, DZSlides, or S5 HTML slide shows. It can also pro‐ duce PDF output on systems where LaTeX is installed. All documentation changes can be submitted as changes to markdown and we can attempt a periodic documentation refresh on gluster.org.
