I just tested my 2nd 1TB gmirror device on another system with FBSD 7.2.=A0= I was getting full throughput on the drive and no lockup using bonnie++ an= d also monitoring with gstat. I then moved those drives back on my main server.=A0 When I booted the syst= em I hung on the 320GB gmirror devices.=A0 Previously the 1st 1TB gmirror a= nd 320GB gmirror were attached to the integrated USB ports on the motherboa= rd.=A0 I moved the 320GB gmirror to a PCI USB adapter. The 2 320GB drives in the gmirror were da5 and da6.=A0 Here's what I saw on= the console: (da6:umass-sim6:6:0:0): SYNCHRONIZE CACHE(10).

My initial design goal was cheap, hot-swappable storage.=A0 I am only using= a 100MB network currently so throughput on the storage is not a problem as= I can't push the data to/from the drives faster than what my network reque= sts are.=A0=20 I first tried my setup on 7.0, then migrated to a newer PC, then upgraded t= o 7.2.=20 =A0 I have the following USB drive setup: 1 320GB gmirror (320x2) + gjournal + ufs2 1 1TB gmirror (1TBx2) + gjournal + ufs2 1 150GB gjournal=A0 + ufs2 I also have another 1TB gmirror (1TBx2) + gjournal but removed it.=A0 The s= ystem crashed when I used these drives (bacula or bonnie++) so I pulled the= m to test on another system. Recently my stability issue has been when I have been writing data to the 1= 50GB gjournal drive from the 320GB gmirror device (USB device -> USB device= ).=A0 It will be working fine, then all I/O stops on the 150GB drive.=A0 Th= e system remains responding to other USB devices etc. for a while.=A0 I try= rebooting and the system crashes with gjournal errors (didn't write down, = but I will later).=A0=20 Every time this happens the 1TB gmirror comes up fine but one of the 320GB = providers is missing.=A0 No problem after 'gmirror forget' and 'gmirror ins= ert'.=A0 Everything rebuilds fine.=A0 The 150GB gjournal drive is fine afte= r a 'fsck -y'. I do pair the gmirror drives to the same USB adapter.=A0 Found out after in= itial testing with multiple USB adapters that they do not appear standard e= nough to cross adapters like I would for a production server at work to pre= vent SPOF with an adapter. I have tried Linux as well with softraid and LVM2 on the same hardware.=A0 = It worked fine until I applied software updates and the udev took 30+ minut= es to boot.=A0 I went back to FreeBSD.=A0 Even when I crashed I was back up= in 2-5 minutes. I can and will provide more detail if requested.=A0 My concern is that the = issue seems to continue no matter what hardware/OS changes I try.
