Fix mount helper Several issues related to strange mount/umount behavior were reported and this commit should address most of them. The original idea was to put in place a zfs mount helper (mount.zfs). This helper is used to enforce 'legacy' mount behavior, and perform any extra mount argument processing (selinux, zfsutil, etc). This helper wasn't ready for the 0.6.0-rc1 release but with this change it's functional but needs to extensively tested. This change addresses the following open issues. Closes #101 Closes #107 Closes #113 Closes #115 Closes #119 2011-03-05 02:14:46 +03:00			`SUBDIRS = zfs zpool zdb zinject ztest zpios mount_zfs`
Multipath device manageability improvements Update udev helper scripts to deal with device-mapper devices created by multipathd. These enhancements are targeted at a particular storage network topology under evaluation at LLNL consisting of two SAS switches providing redundant connectivity between multiple server nodes and disk enclosures. The key to making these systems manageable is to create shortnames for each disk that conveys its physical location in a drawer. In a direct-attached topology we infer a disk's enclosure from the PCI bus number and HBA port number in the by-path name provided by udev. In a switched topology, however, multiple drawers are accessed via a single HBA port. We therefore resort to assigning drawer identifiers based on which switch port a drive's enclosure is connected to. This information is available from sysfs. Add options to zpool_layout to generate an /etc/zfs/zdev.conf using symbolic links in /dev/disk/by-id of the form <label>-<UUID>-switch-port:<X>-slot:<Y>. <label> is a string that depends on the subsystem that created the link and defaults to "dm-uuid-mpath" (this prefix is used by multipathd). <UUID> is a unique identifier for the disk typically obtained from the scsi_id program, and <X> and <Y> denote the switch port and disk slot numbers, respectively. Add a callout script sas_switch_id for use by multipathd to help create symlinks of the form described above. Update zpool_id and the udev zpool rules file to handle both multipath devices and conventional drives. 2011-06-22 03:18:27 +04:00			`SUBDIRS += zpool_layout zvol_id zpool_id sas_switch_id`
