My problem from the other day was rebuilding a raid when I got ecc errors on a different disk than the one being rebuilt. I did a rescan and the ecc errors went away, but the rebuild seemed to be stuck. I contacted 3ware, makers of our raid card and was told to do this:

This seems to be working. I guess I’ll know in a few hours if everything is ok.
If this still doesn’t work, I’m supposed to send 3ware an error log.
./tw_CLI info c0 diag>error.txt
The easy raid rebuild from yesterday turned out to not be so easy. Checking today, I got this message:
//cdfs3> info c0 Unit UnitType Status %Cmpl Stripe Size(GB) Cache AVerify IgnECC ------------------------------------------------------------------------------ u0 RAID-5 OK - 64K 1396.95 ON OFF OFF u1 RAID-5 REBUILDING 89 64K 1396.95 OFF OFF OFF Port Status Unit Size Blocks Serial --------------------------------------------------------------- p0 OK u0 465.76 GB 976773168 WD-WCANU1137212 p1 OK u0 465.76 GB 976773168 WD-WCANU1090078 p2 OK u0 465.76 GB 976773168 WD-WCANU1119743 p3 OK u0 465.76 GB 976773168 WD-WCANU1089924 p4 OK u1 465.76 GB 976773168 WD-WCANU1136981 p5 ECC-ERROR u1 465.76 GB 976773168 WD-WCANU1109927 p6 DEGRADED u1 465.76 GB 976773168 WD-WCAPW5103756 p7 OK u1 465.76 GB 976773168 WD-WCANU1125288
This does not look good at all, but the disk seems to be ok. So I tried this:
//cdfs3> /c0 rescan Rescanning controller /c0 for units and drives ...Done. Found the following unit(s): [none]. Found the following drive(s): [none]. //cdfs3> info c0 Unit UnitType Status %Cmpl Stripe Size(GB) Cache AVerify IgnECC ------------------------------------------------------------------------------ u0 RAID-5 OK - 64K 1396.95 ON OFF OFF u1 RAID-5 REBUILDING 89 64K 1396.95 OFF OFF OFF Port Status Unit Size Blocks Serial --------------------------------------------------------------- p0 OK u0 465.76 GB 976773168 WD-WCANU1137212 p1 OK u0 465.76 GB 976773168 WD-WCANU1090078 p2 OK u0 465.76 GB 976773168 WD-WCANU1119743 p3 OK u0 465.76 GB 976773168 WD-WCANU1089924 p4 OK u1 465.76 GB 976773168 WD-WCANU1136981 p5 OK u1 465.76 GB 976773168 WD-WCANU1109927 p6 DEGRADED u1 465.76 GB 976773168 WD-WCAPW5103756 p7 OK u1 465.76 GB 976773168 WD-WCANU1125288
That’s good. Now, I know the disk p6 is good because it was just replaced. I’m unsure now, if the rebuild will continue without problems or if I need to restart it. I think I’ll leave it for a while to see if things start working again. If it stays stuck at 89% for a while, I’ll run the rebuild command again.
I tried to reissue the command and got the following:
//cdfs3> /c0/u1 start rebuild disk=6 Sending rebuild start request to /c0/u1 on 1 disk(s) [6] ... Failed.

So I think I’ll just have to leave it and hope that it finishes.
Fdisk doesn’t always work properly on disk sizes over 2TB. In our new servers, we’ve been having 3TB raids installed. Here are the instructions for setting up the disk.

Until I find a place to store info on all the raids and disks that I’ve replaced, this blog will have to do. So here is the latest replacement.

Download the plugin from wherever it’s located. Put the file in the wp-content/plugins folder and change permissions to 644 root:apache. Then, just reload the plugins page in wordpress and activate the new plugin.
Exmh was complaining about libpng not being the same version as what was used to compile the program. Since exmh is pretty old, this is not unusual. The package that we needed was libpng10, here is the description:
The libpng10 package contains an old version of libpng, a library of functions for creating and manipulating PNG (Portable Network Graphics) image format files. This package is needed if you want to run binaries that were linked dynamically with libpng 1.0.x.
Unfortunately, this package is not included with RHEL5. (It’s only in RHEL4 and RHEL3.) I did find a copy on the web and installed it so that exmh no longer complains about the images.
The rpm is saved in /system/kickstart/install/additions.

Got the message above, which showed that p5 failed. Since it was already missing, according to the tw_cli software, the remove command failed. So, I put a different disk in (one that had been in another raid) and got the following:
//pnn> info c1 Unit UnitType Status %Cmpl Stripe Size(GB) Cache AVerify IgnECC ------------------------------------------------------------------------------ u0 RAID-5 DEGRADED - 64K 1629.74 OFF OFF OFF u1 RAID-5 INOPERABLE - 64K 1629.74 OFF OFF OFF Port Status Unit Size Blocks Serial --------------------------------------------------------------- p0 OK u0 233.76 GB 490234752 WD-WCANY1850307 p1 OK u0 233.76 GB 490234752 WD-WCANY1790824 p2 OK u0 233.76 GB 490234752 WD-WCANY1851579 p3 OK u0 233.76 GB 490234752 WD-WCANY1789766 p4 OK u0 233.76 GB 490234752 WD-WCANY1796905 p5 OK u1 233.76 GB 490234752 WD-WCANY1787889 p6 OK u0 233.76 GB 490234752 WD-WCANY1788952 p7 OK u0 233.76 GB 490234752 WD-WCANY1788819
Crazy. It now thought that p5 was part of another raid (u1) on this controller.

Yep, it now shows two bad units on c1. I tried rescanning and even removing the disk and reformatting it, but it didn’t matter. The only solution was to delete that second unit, which is always nerve-wracking, for fear that I’ll delete the raid I wanted to keep. So after quadruple-checking the command, I ran:

That deleted the extra unit and let me start the rebuild on disk 5 of the degraded unit.
I got an email alert this morning letting me know about a disk failure in one of our raids.

That’s bad. Disk p5 disappeared as well. I tried rescanning a few times, but that didn’t find it. So I tried just rebuilding disk 3 anyway.
//cdfs1> /c1/u0 start rebuild disk=3 Sending rebuild start request to /c1/u0 on 1 disk(s) [3] ... Failed. (0x0B:0x0033): Unit busy
That didn’t work either. So I tried removing disk 3 and putting it back in.

Nope, that didn’t work either. So I decided to remove disk 5 (but I never took it out of the case) and rescan.

Ah, success. I don’t know why disk 5 got goofy all of a sudden, but I could now rebuild the new disk.

What was weird was that this computer has two raids. The errors that I got were all from raid c1. After it had been rebuilding a while, I went to check on it and found that disk 3 in raid c0 was now showing up as NOT-PRESENT because stupidly above, I had run /c0 remove p3 instead of /c1 remove p3. So, I rescanned c0 and rebuilt the drive on raid u0.
