Is ZFS more solid than in Linux?
Linux does the same with bad RAM, and you'll often see that in large installations. (Monitoring should check you have the number of DIMMs and CPUs expected, modulo a fiddle factor for reported memory size, which depends on BIOS.)
- retrovm 7y agoLinux chipkill ECC support is a crapshoot. Intel redesigned it all for Skylake and later CPUs and Linux still hasn't caught up with the changes. Some of it mostly works on pre-Skylake, but often doesn't. I've seen Linux killing processes that have a bad physical page mapped, but the process just gets killed in a loop because the kernel is too stupid to actually take the page offline.
- gnufx 7y agoSo, does IllumOS support Skylake properly? Anyhow, the implication that it's unique in handling bad memory is unfounded. (I haven't run Skylake or SunOS/Opensolaris at any scale, but I have substantial experience with large Linux-based HPC systems with memory problems and not hit such problems.)
- retrovm 7y agoI seriously doubt that illumos has the edac sorted out on newer parts. That's why i recommend running it in a VM.
- hylaride 7y agoIs ZFS more solid than in Linux? Yes, considering ZFS was originally developed by Sun for Solaris. It's been 8 years since I've been a Solaris admin, but we ran production DB workloads on JBODs with ZFS with no problems. Though I've not run ZFS on linux myself, I've heard that many of its issues stemmed around the fact that due to CDDL/GPL incompatibilities, they couldn't have ZFS in the kernel until very recently.
