comment Heartbleed: What is it and what are options to mitigate it?
@EEAA, I was responding to your comment that you can't always shutdown.

@EEAA, it is also the least desirable response and, as you pointed out, not always possible.

@WayneConrad, I would hope that sites would have shut down and patched already.

comment Files missing after RAID1 restore
Most likely you had the array go degraded a year ago and did not notice, then the other drive died completely, so you have recovered using the out of sync drive.

Send out an email to your users reminding them never to click links in an email like that, but instead to open a browser and go to the correct web site that they have used before instead?

comment Heartbleed: What is it and what are options to mitigate it?
@EEAA, "shutdown your servers" does not mean you have to pull the power. It means shut down ( or reconfigure to disable ssl/tls ) apache, or whatever service is doing the serving.

comment Monday morning mistake: sudo rm -rf --no-preserve-root /
This sure seems like trolling to me. You can't accidentally type --i-really-mean-delete-my-whole-root.

@pepoluan, because the question was asked in 2010?

comment How should mains power be conditioned for devices not protected by a UPS?
I have to say this is nonsense. The modern PC power supply ensures clean DC power to the components and is fairly tolerant of mains over/under voltage. When the mains gets too bad, they fail gracefully, in other words, they shut down rather than feed bad DC to the components.

comment Improving Hard Drive controllers and Software RAID
Seagate is in fact selling hybrid drives with on board flash so if you get some of them you can get the performance of a battery backed write cache without the need for an expensive controller.

What does "ECC error status" mean? What do the SMART stats say?

comment smartctl reports Current Pending Sectors as 2, but a long test doesn't find any errors
You clear the pending count by trying to write to the sector in question. Either it succeeds, or is remapped to the spare pool, thus it is no longer pending. The odd thing is that the drive claims that there are two bad sectors awaiting relocation, and at the same time, that there are no bad sectors. This makes no sense.

comment Is it possible that just one bit switches so my file shows me a letter “Q” instead of a “S”
@derobert, hence why I qualified my statement with only a single bit flip. It is theoretically possible ( though you have a better chance to win the lottery and get struck by lightning on the same day ) to have the raw bits scrambled in such a way as to flip the target bit after the reed-solomon error correction, and then satisfy the ecc, but it involves flipping many bits, not just the one. This would leave the rest of the contents of that sector unrecognizable.

Failing the whole block read is exactly what drives do when they get an uncorrectable error. It is impossible to have only a single bit flip in the user data part of the sector, and go undetected. The bit must have been flipped when it was written to the disk.

@HaukeLaging, hence why I asked for the full smartctl output.

@HaukeLaging, of course it will?
