PowerEdge 1800 SATA Cerc 6 squeals with high-pitch tone during format
Posted on 2009-04-16
I have a PE1800 (Cerc 6) that I bought with 3 * SATA 750GB disks but recently upgraded to 1TB * 6 SATA disks.
The card cannot make a >2TB array, so there are two arrays: Cerc Arr012 and Cerc Arr345, each made of 3 * 1TB disks in RAID 5 for a total of 1.9 TB per array.
I installed and configured this server as an R-Snapshot backup server, but during initial testing, I realized that I only had 2TB of space to use for backups because LVM could only go up to 2TB in a volume. I needed to repartition, so I backed up the system using rsync and am trying to reinstall RHEL5.
At first, I tried to put the LVM-usable disk space from Arr012 and Arr345 into the same Volume Group so that I could have one big /srv partition for backups:
Arr012: sda1-/boot + sda2-swap + sda3-LogVol00
LogVol00 = swap + /(root) + /var + /tmp + /srv
However, when Disk Druid got to the formatting stage, a continuous high-pitched beep or whine or alarm sound emanated from the case. It just kept going for about 10 minutes while I was Googling the issue. Finally, I shut the machine down and started the installation over again.
I then tried this:
Arr012: sda1-/boot + sda2-LogVol00
LogVol00 = swap + /(boot) + /var + /tmp + /srv
LogVol01 = /srv2
I divided it up like the above and then set it to format. It did not squeal like the first try, but it does squeal for a little and then go quiet as it formats. And the format is taking forever. I went home after 20:00, and it was still formatting /srv2. I cannot tell whether it is stalled or not, but I would liek to know why the high-toned squeal.
Should I worry about this sound?
Can I rely on this server in this condition?
Should I give up on this machine?
