VOLUME SHARING El Capitan to Sierra

Alexander Forbes
Sorry in advance for the length. This kind of problem requires a lot of questions, so I’ve supplied the steps I’ve taken so far to try solving a volume sharing problem.

I have a Large RAID volume ‘HT101RAID' I use as a repository for archives and data storage I don’t need on Dropbox. I believe I occasionally  used to be able to Share it (read and write) with my other machines on my local network.

The while purpose of this exercise is to get away from swapping and syncing portable drives when I have a network. HT101RAID is also backed up to another RAID, so I have double or triple redundancy.

Having trouble dropping files onto the volume pointed on my iMac, I started looking at permissions again and searching the web. HT101RAID works as a “true” shared volume every once in a while, but usually I only get read permission, even on cold starts of both machines. These reflect the same kind of complaints and questions posed on the web.

On my 2009 Mac Pro, the Share checkbox becomes unchecked on every start or reboot. I have to reset the flag manually - but, to no avail. I’m getting a little tired of fiddling with permissions on settings on something that used to work consistently and  transparently, even with my Windows 7 PC. The Mac Pro is capped out at El Cap due to its age. My iMac is on Sierra. Each OS us current on updates.

‘HT101RAID’ resides on my Mac Pro through an eSata add-on card.

Get Info permissions on this HT101RAID are set to read & write for me, Administrator and System. ‘Me’ and Administrator have Adminisratior positions. Using the “Gear" I have applied volume read/write permissions to every folder and subfolder within the come using the procedure outlined by Apple:


All my machines have an Administrator and Alexander Forbes account. All are set to Administrator privileges. All use a common login username and password.

I’m getting a little tired of fiddling with permissions on settings for something that used to work consistently and  transparently, even with my Windows 7 PC.

I’ve seen some web posts recommending sudo and Terminal to solve similar problems. I can do basic Terminal and unix/linux commands, but I’m reluctant to apply a complex command I don’t even understand and for which no results were mentioned or substatiated. In my experience, I’ve found many of those “code suggestions” are actually armchair on the fly, and, at the very best, don’t work.

It’s odd that I have full network read/write access to a portable USB3 drive running on the Mac Pro. I’d be very reluctant to give up the speed and redundancy of a four-drive RAID101 installation.

I don’t have the budget for a newer “old” Mac Pro that will run Sierra - for the time being - nor for some kind of Thunderbolt RAID array setup on my Mac Pro.

Suggestions? Might installing OS Server for El Capitan be likely to ease the sharing of all volumes set to Sharing? I still use the Mac Pro for “regular work” - does installation of Server disrupt file storage, apps or workflow? How do others of you use your Server installations and what has been your experience?

Regards,

Alex

The first thing is that eSATA is kind of a mess and no so much a standard as a hack or a kludge. I would guess that all the problems are rooted at the eSATA card, the cable, or the connector on the RAID or Card. I’ve always found eSATA setup to be flakey and prone-to failure, YMMV.

The power-on order might be an issue as well. Does your RAID fully startup if the computer is off, or does it go into sleep mode when it doesn’t see a host? If the latter (which is common), then the startup sequences might be getting out of sync.

Also, the type of volume on your RAID might be part of the issue, depending on what it is and how the RAID handles permissions/ACLs/etc.

Or the issue could be the RAID controller of the kext you probably needed to install to drive the card.

My iMac mounts several network shares (Synology, Windows, other Macs, Drobo) and has none of the sorts of issues you are experiencing.

In short, this is not likely to be a problem with your Mac.

Thanks! :-) “Flakey” describes this situation perfectly. I'll look into re-plugging the RAID into the internal USB3 card I also installed in the Mac Pro. Time to blow the dust out anyway.

I configured the four drives as RAID101 using Disk Utility around a couple of years ago. The four are identical 2TB Hitachi HUA723020ALA841 Media drives partitioned as GUID Partition Map. I still have 3.03TB Available. Disk Utility shows “Owners enabled” as “Yes." 

This is an internal installation, not self-powered external. Typically, I start the Mac Pro first and then bring up iMac. Bring up Mac Pro last offers a slight improvement, allowing iMac-Mac Pro transfer of a test file to a folder named “TEST,” but NOT another named “DEV” which also shows “Shared”  in its individual folder Get Info. I’d say this is a fair example of Flakey.

If the eSATA card is problematic, then it doesn’t sound like installing OS Server would likely improve the gambling "odds” of correcting this situation.

OWC offers a “ThunderBay 4” four bay Thunderbolt 2 drive enclosure for $397.50. Seems this might bypass the whole issue and take a load off Mac Pro. My paltry IRS refund will just about pay for it.  This could run on my 2011 iMac. There is no reason why one machine HAS to host the shared volume. Opinions?


Thanks again,

Alex

I have one attached to my 2013 MacPro and am very pleased with it. My only complaint is that I think the period of inactivity before the disks spin down is too short.

I'd look at  Synology (a 4 drive DS416 is about $350). It's network addressable storage instead of locally attached, but it is also a quite decent server.

I use my Synology for backups, Plex, web serving, VPN, cloud storage and syncing, and a few other things.

Thanks very much anyway, but I ordered an OWC 4-bay and it will be here tomorrow …
