Enhancements in the 6.1.1 release The 6.1.1 release includes the new HP IBRIX X9730 Network Storage System. This system replaces the X9720 system and includes new storage array controller hardware, 3TB HDD support, simplified installation, and diagnostics. For X9320 systems, the 10GbE version now has two cards providing four network connections at 10 GbE. The following software features are new in this release: • New GUI wizards to configure user authentication and file shares.
The following output shows the relevant portion of the output from the ibrix_fs -f fsname -i showing how newer segments (37,38,39) appear on a file system originally created with compatibility mode enabled. NOTE: The 9th column (“FFREE”) which is your total available inode count per segment for the original segments 66 Million per segment and that of the newer 64 bit segments of 1 billion per segment.
• The ibrix_datavalidation -c option has changed to ibrix_datavalidation -s. • Fusion Manager maintenance mode is now called nofmfailover mode. When a Fusion Manager is in this mode, it no longer participates in Fusion Manager failover. The mode is invoked as follows: ibrix_fm -m nofmfailover • The default port for the X9000 SNMP agent has changed from 5061 to 161. The SNMP port number is not user configurable. • SNMP v3 is not supported. Software snapshots Upgrading pre-6.
is deleted and replica is promoted as the original file. These replicas have to be marked with the directory quota ID same as that of the original master file, but that was not occurring. As the original file is deleted post replication, the directory quota accounted for it gets decremented. Since the newly created file was not marked with the directory quota ID, it was never accounted for. As a result, a reduction in quota usage was shown post replication.
Fixes in the 6.1.2 release • Resolution for a critical potential security issue. Refer to the Security Bulletin available at: https://h20566.www2.hp.com/portal/site/hpsc/public/kb/docDisplay/? docId=emr_na-c03510876 • The CIFS shadow copy feature that was disabled in the 6.1.1 release has been renabled by default in the 6.1.2 release. For more information about the feature, see the HP IBRIX X9000 Network Storage System File System User Guide.
• When a file system containing a CIFS share was replicated in continuous mode, file deletions from the CIFS share were not propagated to the target. • The NIC monitor failed with a segmentation fault. • The HP IBRIX X9000 Network Storage System File System User Guide did not explain that when a quotas file is imported, the quotas are stored in a different, internal format. When a quotas file is exported, it contains lines using the internal format.
CIFS • CIFS and X9000 Windows clients cannot be used together because of incompatible AD user to UID mapping. You can use either CIFS or X9000 Windows clients, but not both at the same time on the cluster. • The X9000 CIFS server does not support connections from Linux SMB clients. The workaround is to use NFS for Linux. • Alternate Data Streams (ADS) are not supported.
1. Disable the SMB2 protocol on all nodes: ibrix_cifsconfig -t -S SupportSmb2=0 2. Restart the CIFS service on all nodes: ibrix_server -s -t cifs -c restart You may also need to restart the Windows client, as the original negotiated protocol, SMB2, might be cached by the client. Restarting the client renegotiates the protocol back to SMB1. • Be sure to remove Active Directory users from the X9000 share admin list before removing them from Active Directory.
Block snapshots • Snapshot creation may fail while mounting the snapshot. The snapshot will be created successfully, but it will not be mounted. Use the following command to mount the snapshot manually: ibrix_mount -f -m / • Quotas are disabled on block level snapshots (for example, MSA2000 snapshots) and the quota information from the origin file system is not carried to the block level snap file system. Block level snapshots are temporary file systems that are not writable.
Data retention and validation • The ibrix_reten_adm command fails if the date string specified with -e contains spaces. As a workaround, use the following command to enter date strings containing spaces: /usr/local/ibrix/sbin/ibr_reten_adm -e expire_time -f FSNAME -P PATHLIST • The ibrix_vs_snap command cannot delete a block snapshot file system that is enabled for data retention. Instead, use the ibrix_fs command with the -R option.
2. Run the following command to exclude all files in the .webdav directory: # ibrix_avconfig -a -E -f FS1 -P /FS1/.webdav/ -x '*' 3. Reset the immutable bit on the .webdav directory: # chattr +i .webdav/ 4. Exclude all files in the .DAV directory for each HTTP/WebDAV share created: # ibrix_avconfig -a -E -f FS1 -P /FS1/httpshare/.DAV/ -x '*' Segment evacuation • The segment evacuator cannot evacuate segments in a READONLY, BROKEN, or UNAVAILABLE state.
components to toggle from Up, to Stale, and back to Up. Common causes of failures in the monitoring system include: ◦ Reboot of a file-serving node ◦ Network connectivity issues between the management console and a file serving node ◦ Resource exhaustion on a file serving node (CPU, RAM, I/O or network bandwidth) While network connectivity and resource exhaustion issues should be investigated, they can occur normally due to heavy workloads.
service snmpd restart • On X9320/X9720 systems, the virtual SAS manager and VC connect manager must be configured manually for HP Support. • On HP SIM 7.1, X9320/X9300 nodes are discovered as “HP X9320 NetStor FSN” if MSA storage is registered on the cluster nodes. This does not affect sending alerts to HP Support. Upgrades • System User login credentials are backed up and restored during upgrades. However, any user data is not retained.
Documentation changes and additions File system support for 32-bit and 64-bit mode The section “Creating a file system” on page 12 in the HP IBRIX X9000 Network Storage System File System User Guide contains out-of-date information about 64-bit mode and 32-bit mode. In the 6.1.1 and later releases, file systems are created in 64-bit mode by default. See “Implementation changes in the 6.1.1 release” (page 6) for more information.
Upgrades The upgrade procedure is provided in the administrator guide for your storage system. Contact HP Support for assistance with the procedure. Compatibility/Interoperability Note the following: • Every member of the cluster must be running the same version of X9000 software. • The cluster must include an even number of file serving nodes. • All X9000 clients must be running 6.0 or later. Documentation feedback HP is committed to providing documentation that meets your needs.
