* snapview-server: register a callback with glusterd to get notificationsRaghavendra Bhat2014-09-081-0/+47
| | | | | | | | | | | | | | | * 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). Instead of that register a callback with glusterd so that glusterd sends notifications to snapd whenever a snapshot is created/deleted and snapview-server can configure itself.

| | | | | | | | | | | | | | | | | | | | | Problem: NFS allows exporting subdirectories but there is not support for providing AUTH on per directory basis. Fix: Modified nfs.export-dir to include AUTH parameters e.g. nfs.export-dir "/dir1(10.1.1.2),/dir2(10.1.1.0/24|host1) During mount operation NFS will check if the IP from where the connection is made is configured in the AUTH parameter, else the mount operation will fail with EACCES error. Updated admin-guide and volume set help message.

* 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.

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.
