ZFS on Linux: Zpool import failed

We upgraded a Proxmox box today which was running ZFS and ran into this rather scary looking error: zpool: ../../lib/libzfs/libzfs_import.c:356: Assertion `nvlist_lookup_uint64(zhp->zpool_config, ZPOOL_CONFIG_POOL_GUID, &theguid) == 0′ failed.

A simple: yum install…

A customer upgraded from 13.04 to 13.10 and their internal wiki was broken afterwards; for a simple Apache install where the wiki was installed at the web root and all access was via the LAN (thus they were happy with not restricting the access), the fix was to add: <Location /> Require all…

New Mediawiki install produces error “Fatal exception of type MWException”

Saw this on a new Mediawiki install where all of the optional extensions were selected, LocalSettings.php had been uploaded to the server and that’s as far as it would go. To fix, open up LocalSettings.php and comment out the line: require_once( “$IP/extensions/LocalisationUpdate/LocalisationUpdate.php” ); You should now be able to refresh the…
