This field is omitted if no problems are found. When a corrupted block is removed, the next scrubbing pass recognizes that the corruption is no longer present and removes any trace of the error from the system. Information for preventing failures is provided as well. This log is rotated whenever a complete scrub of the system finishes. Source
I will paste some excerptsBefore upgrade to NW6SP402005 08 16 03:03:39 System Not Synchronized 02005 08 17 01:22:39 Agent requested synchronization. 02005 08 17 01:23:22 NSS Pools synchronized02005 08 17 01:23:22 This section describes how to interpret zpool status output in order to diagnose the type of failure and directs you to one of the following sections on how to repair the If the state is anything but ONLINE, the fault tolerance of the pool has been compromised. Moreover, such errors are typically the result of a driver problem accompanied by its own set of error messages. http://www.novell.com/support/kb/doc.php?id=3400559
In this case, the controller should be replaced at which point the disks will again be available. Verify the recovery by using the zpool status -x command.

If you are going to replace a disk (c1t3d0) with another disk (c4t3d0), then you only need to run the zpool replace command. To run Refresh, follow these steps: Restart your computer Boot from the Windows 8/8.1 installation media (the original DVD or USB drive). If all components of a mirror are removed, if more than one device in a RAID-Z (raidz1) device is removed, or if a single-disk, top-level device is removed, the pool becomes I guess Novell and/or St.
ZFS tries to avoid this situation, though arbitrary corruption is always possible given the qualities of the underlying storage. Determining if a Device Can Be Replaced Devices That Cannot be Replaced Replacing a Device in a ZFS Storage Pool Viewing Resilvering Status Determining if a Device Can Be Replaced For However, the information provided in this document is for your information only. ArghhI hate backup exec!!!
This field is omitted if no problems are found. If the device causes a top-level virtual device to be unavailable, then nothing in the pool can be accessed. However, if two disks in a four-way RAID-Z (raidz1) device are faulted, then neither disk can be replaced because not enough replicas from which to retrieve data exist. Restore the faulted configuration or corrupted data from a backup.
Which is why we created Linux Server Hacks, Volume Two, a second collection of incredibly useful tips and tricks for finding and using dozens of open source tools you can apply An I/O error has compromised integrity." Creating or deleting files on NSS volumes returns an error Error: "NSS-2.70-5004: An I/O error has compromised file system integrity." The volume dismounts and goes Novell recommends that this parameter stay at its default setting of ON.Edit these two filesMy server is a Novell Small Business setup. Notifying ZFS of Device Availability Once a device is reattached to the system, ZFS might or might not automatically detect its availability.
Sufficient replicas exist for the pool to continue functioning in a degraded state. This command describes only pools exhibiting problems. This parameter is ON by default and will automatically set the file cache maximum size appropriately for the server during operation.

For example: # zpool replace tank c1t1d0 This command takes an unformatted disk, formats it appropriately, and then begins resilvering data from the rest of the configuration. These actions cause ZFS to forget that any pools exist on the system, preventing it from trying to access the bad pool causing the problem. http://crearesiteweb.net/an-error/an-error-occurred-while-copying-files-to-the-backup-volume.html There was no need to change this parameter on my system.> FILE - SYS:\ETC\SMS\TSA.CFG > set> Cache Memory Threshold:> 10This file contained the value 25.I'd set it to 10, and I'll
Easy Recovery Essentials will start analyzing the selected drive for problems. Even so, you might be able to recover from this corruption without restoring the entire pool. Back up your restored configuration, if applicable.

To do so, follow these steps to access chkdsk: Restart the computer with the original installation media (that's either the DVD or the USB flash drive) If you don't have the The second section of the configuration output displays error statistics. Object data – In this case, the corruption is within a specific file or directory. Damaged Devices in a ZFS Storage Pool The term “damaged” covers a wide variety of possible errors.
Press Enter Then type: bootrec /fixboot Press Enter Then type: ren BCD BCD.Backup This will create a backup of your current BCD file. With the pool configuration and dataset layout, you can reconstruct your complete configuration after destroying the pool. see: http://www.sun.com/msg/ZFS-8000-72 scrub: none requested config: NAME STATE READ WRITE CKSUM dbpool FAULTED 0 0 1 corrupted data c1t1d0 ONLINE 0 0 2 c1t3d0 ONLINE 0 0 4 The recovery process Compiled by experts, these hacks not only give you the step-by-step instructions necessary to implement the software, but they also provide the context to truly enable you to learn the technology.
