We had a power cut today and when I powered up the RAID 5 drive the following came up:
Raid Error E13 Array1 Error
HD Error E23 HD3 is Faulty
Operational Mode I12 Degrade Mode
Can I have some advice how to resolve this please?
Replace the HDD and restructure the array
Question...
I have 4 x 500GB drives at the moment, can I replace the dead drive with a 1TB HD restructure the array and then replace the other 500GB HD restructuring the array as I do one drive swap at a time.
There is virtually no difference in price between 500Gb and 1Tb drives so It would be a good opportunity to upgrade the drive storage.
If you replace the 500GB drive with a 1 TB and resynch it into the array it will scale the drive down to 500 GB. I would just replace all of the drives and TFTP the firmware back on to it.
I have a similar problem on my Terastation (HS-DH0.0TGL/R5).
Raid Error E13 Array 1 Error
Operational Mode I12 Degrade Mode
HD1 Error E23 HD1 is faulty
Several months ago, I replaced a drive in this Terastation and everything went well. At that time, I purchased two new drives, keeping one as a spare. These drives were IDENTICAL to the drives installed on the Terastation (Samsung Model HD501LJ, 500Gb).
I replaced HD1 with the remaining new drive I had, but am still getting the same messages. I've done some reseach on other users with the same experience and many are now saying that Buffalo Technologies is suggesting it's a faulty raid controller. If this is the case, is it possible to change the raid controller? I am about to order several Terastation Pro II units for my business, but am alarmed about how many instances of raid controller failures I've seen. I would just like to know if there is any recourse in the event the HDs are not the problem.
Thanks!
I have been living with this error (E13) for quite some time and would like to have it resolved. I have replaced the faulty drive, re-structured the array, and reset to factory defaults. Nont of these seem to work, and I am in an endless loop of resetting.
I REALLY don't want to wipe the drive and reload my data.
Does anyone have a solution?
PS: TeraStation Pro iSCSI TS-IGL/R5
After you did that have you tried to Reinit the unit through the user interface?
Log into the Web Admin then go to Maintenance>initialization>restore.
