Enjoy v5 Gary

Yup, something in the newer SMB broke transfer speeds. Did you see my Windows tweaks that allow you to use the newer SMB while reclaiming the speeds? Works great... And actually helps with other Windows network speeds (including speakeasy / Internet speeds)

Earlier v6 post tunables shaved about 2 hours off of the 15.5 hour check. It took me a LONG time to tweak WRITE performance back up.... That one did bother me a great deal.. . But now that I'm back up to v5 write performance I am happy. Note that the READ is a bit limited on speed during the parity check.

Average speed: 69.5 MB/sec Yup... that's right... the parity check speeds fully tweaked are simply not as fast as v5. For me, the added features of v6, including dual parity, are too great a benefit compared to the trade-off of 1 day per month where the check now takes 16 hours rather than 10. I can eek out a little faster parity check by disabling 'most' of my plugins above... but it is not significant. *Something has changed between version 6.2 and 6.2.4 *The parity check has gone from well over 71 (I believe it was ~100) to 69.5 *Note that the location (heated master bedroom closet, near the ceiling) is significantly warmer during the winter.

I've tweaked 'acceptable' performance out of this Gary. I'm away from the house ATM, but when I return I'll share specifics. I even have dual parity. The cache disc is a SSD. All disks are 4 TB, identical models. Minimal plugins (cache directory is one of them). I had to run the disk tunables script as my v5 and default tunables sacked. I also had to alter some settings on the WINDOWS machine. Parity speed speeds are much faster. Writes are around 100 using Windows, and around 60? using Tera copy.

The one time I had a post-read failure that said my drive was not zeroed like yours did, it was because of bad RAM. Do memtest immediately! I had the exact same issue

If you are located near NW Indiana I'll 'build' it at no cost. Just for kicks n giggles

Awesome! Machine was segregated from the network, Pre-Clear update took, and selected cancel when prompted to install share data. Right now we fill the entire disk with random info before the Pre-Clear. It will be nice to no longer need a separate machine for this

Most of my communication here is in regards to personal machine tinkering... not the office use. Please, no need to apologize I am certain this use case represents a VERY small fraction of Unraid users, nevertheless it thrills me in how responsive you are in meeting it! You are a fantastic contributor to fleshing out the core functionality I am looking forward to installing the optional reporting on my 2 home machines

Thank you! this WILL be turned on my home machines the ability to ensure that reach outs will not happen automatically (opt-in) ... And loosing the word TOR from email notifications (which is what triggered the response) when not opting-in would help a great deal too!

The firewall is only open at certain days/times and only when certain conditions are met. The firewall controls are separate from the rest of the network. The firewall slams shut if certain kinds of traffic are detected (TOR being one of those) Unraid is not work's primary backup. It is an onsite backup to the backups. We replaced our Ubuntu based backup years ago as Unraid was more stable for this function. We are required to have this onsite backup and it must use a different OS/filesystem from the primary data. CA Auto Update is scheduled to run at a time when other machines have access to reach out for updates while the firewall is open. As such, no user has access to touch files. A script from another machine runs via SSH which stops samba, unmounts each disk, etc The firewall will not open if samba is detected on the network. Before the start of the day, samba and the array is restarted ... I do not have access to manage the firewall or the Samba policies/protocols -> that belongs to a separate independent entity. … Back to the original question. Can the preclear data collection be Opt-In… or at least an option to Opt-Out?

Can data collecting be an opt-in feature PLEASE? both of my home servers and my work server autoupdated the plugin last night. The plugin was not in use on any machine. If this cannot be an opt-in feature I'll sadly have to go back to a v5 build with the JoeL script just for clearing disks at work as we do 3 preclears on all new disks... and 3 preclears on all decommissioned disks and data cannot flow out of the company. While receiving this email was mildly irksome on the 2 home machines... the use of TOR, which is STRICTLY prohibited on any work network, set off a bunch of red flags at work as my business revolves around government/bank/broker/customer confidential information... and I was called in EARLY to investigate who was attempting to breach NDAs to leak restricted information and have been in meetings with the parent company and our customers over what happened for the last 3 hours. I have been very happy with your contributions/work... this update was less than pleasing.

About a tenfold jump in pass mark score... Nice! So.... I also have the D525 in a supermicro flavor.... And while v6 is heavier out the gate than v5, with a little tweaking I was able to get to nearly full write speed back. Disc tunables is a must!

Yeah that was one thing I wasn't sure about. Are you saying that, for the most part, a hidden, unmapped SMB share is ransomeware safe? My gut says it should be since how would any ransomeware know to even find it. I mean, if they're REALLY good they'd write something that sits and waits for a a few days to collect info on hidden shares, but is any ransomwhere doing that? That I do not know. I am assuming your backup software has the mapping info saved as a potentual source of the info? What about SMB use sniffing? No answers, just questions

On your backup: you can still type a hidden share for access. On my second machine no shares are exported to SMB and all are private. I have a VM (ubuntu) that turns on with the local Al shares passed through and the main machines shares mounted as read only users. I use rsync and only copy if new/no delete for media shares. All other shares I use rsync to copy all. Crashplan to cloud, also o machine 2, takes care of historical non-media share off-site backup.

+1 for salty brine's FolderMatch

Some recent Unraid updates had significant changes that required this of most previously installed dockers.

I do not BELIEVE so Squid. By default, CP is optimized for 1TB or 1 Million files. A user needs to manual up this amount at essentially 1 MB / 1TB OR 1M Files to be backed up. if the container is 32 GB (not certain if it is or not)... 1.5-2 is about the max.

Rightclick on the Crashplan Icon in the Crashplan Gui to bring up Crashplan's command interface For 2 MB of memory allocation Enter java mx 2048, restart https://support.code42.com/CrashPlan/5/Troubleshooting/Adjusting_CrashPlan_Settings_For_Memory_Usage_With_Large_Backups

After the move to 6.2? I had to remove the container, add it back, setup CP, Start CP, Add the extra RAM (via the click on icon method), restart CP, then via CP allow re-sync to occur. no problems since

While not difficult per the guide... This would be a nice GUI feature : choose X disks for depreciation , choose new single replacement disk. Adds new disk to configure, copy all data, removes old from configuration,

How did you 'use cache'? My guess is that your' use' need would have been fulfilled with unassigned devices

Nice job on the update OP!
