Unfortunately I can't re-attach the device and force the import, because the device is long gone. It was a single-dev pool, too.

Hello, I have a problem on my backup server. I lost my system hdd and my separate ZIL device while the system crashs and now I'm in trouble. The old system was running under the least version of osol/dev (snv_134) with zfs v22.
After the server crashs I was very optimistic of solving the problems... (2 Replies)

A backup/clone script of ours was recently ran. It normally only clones the rpool and renames in rpoolA. Something must've changed as it found another one of our pools that it shouldn't have.

RNGD(8) System Manager's Manual RNGD(8)
NAME
rngd - Check and feed random data from hardware device to kernel random device
SYNOPSIS
rngd [-b, --background] [-f, --foreground] [-i, --ignorefail] [-o, --random-device=file] [-p, --pid-file=file] [-r, --rng-device=file] [-s,
--random-step=nnn] [-W, --fill-watermark=nnn] [-d, --no-drng=1|0] [-n, --no-tpm=1|0] [-q, --quiet] [-v, --verbose] [-?, --help] [-V, --ver-
sion]
DESCRIPTION
This daemon feeds data from a random number generator to the kernel's random number entropy pool, after first checking the data to ensure
that it is properly random.
The -f or --foreground options can be used to tell rngd to avoid forking on startup. This is typically used for debugging. The -b or
--background options, which fork and put rngd into the background automatically, are the default.
The -r or --rng-device options can be used to select an alternate source of input, besides the default /dev/hwrandom. The -o or --random-
device options can be used to select an alternate entropy output device, besides the default /dev/random. Note that this device must sup-
port the Linux kernel /dev/random ioctl API.
FIXME: document random-step and timeout
OPTIONS
-b, --background
Become a daemon (default)
-f, --foreground
Do not fork and become a daemon
-p file, --pid-file=file
File used for recording daemon PID, and multiple exclusion (default: /var/run/rngd.pid)
-i, --ignorefail
Ignore repeated fips failures
-o file, --random-device=file
Kernel device used for random number output (default: /dev/random)
-r file, --rng-device=file
Kernel device used for random number input (default: /dev/hwrandom)
-s nnn, --random-step=nnn
Number of bytes written to random-device at a time (default: 64)
-W n, --fill-watermark=nnn
Once we start doing it, feed entropy to random-device until at least fill-watermark bits of entropy are available in its entropy
pool (default: 2048). Setting this too high will cause rngd to dominate the contents of the entropy pool. Low values will hurt
system performance during entropy starves. Do not set fill-watermark above the size of the entropy pool (usually 4096 bits).
-d 1|0, --no-drng=1|0
Do not use drng as a source of random number input (default:0)
-n 1|0, --no-tpm=1|0
Do not use tpm as a source of random number input (default:0)
-q, --quiet
Suppress error messages
-v, --verbose
Report available entropy sources
-?, --help
Give a short summary of all program options.
-V, --version
Print program version
