Please help(urgent) - How to simulate transactional data for reliability/survival analysis
...ise above data for reliability/ survival analysis. To begin with below is the transactional data format that i want prepare: Pump-id| Timestamp | temp | vibration | suction pressure| discharge pressure | Flow Above transactional data has to be prepared with below failure modes Defects : (1) Cavitation ? very high in frequency but low impact (2) Bearing Damage ? very low in frequency but high impact (3) Worn Shaft ? medium frequency but medium impact I have used survsim package but that's not what I need here. Please help and guide. Regards, Sandeep

Help to simulate data to model pump failure use case
...ent in 3 months for each Pump is defined. i.e Pump1 would fail 3 times in 3 months, Pump2 would fail 2 times in 3 months, etc. - The failure modes are defined based on the combination of below variables: Failure modes:: -- Bearing damage --> +ve_corr('temprature' + vibration) -- Cavitation --> -ve_corr( +ve_corr(discharge_pressure + flow) + temprature) -- worn shafts --> +ve_corr(discharge_pressure + flow) How should I be generate distributions for the variables listed in the "failure modes" maintaining the correlation stated above.

Upgrade from 3.8.15 to 3.12.5
Hi, I have a 3 node cluster (Found1, Found2, Found2) which i wanted to upgrade I upgraded one node from 3.8.15 to 3.12.5 and now i am having multiple problems with the install. The 2 nodes not upgraded are still working fine(Found1,2) but the one upgraded has Peer Rejected (Connected) when peer status is run but it also has multiple brick that have "Transport endpoint is not connected"

Split brain
Hi, I am having a problem with a split-brain issue that does not seem to match up with documentation on how to solve it. gluster volume heal VMData2 info gives: Brick found2.ssd.org:/data/brick6/data /08aa5fc4-c9ba-4fcf-af57-72450b875d1a/images/d1164a9b-ba63-46c4-a9ec-76ea4a7a2c45/82a7027b-321c-4bd9-8afc-2a12cfa23bfc

Upgrade from 3.8.15 to 3.12.5
I believe the peer rejected issue is something we recently identified and has been fixed through https://bugzilla.redhat.com/show_bug.cgi?id=1544637 and is available in 3.12.6. I'd request you to upgrade to the latest version in 3.12 series. On Mon, Feb 19, 2018 at 12:27 PM, <rwecker at ssd.org> wrote: > Hi, > > I have a 3 node cluster (Found1, Found2, Found2) which i wanted
