>Description:
I have an Ubiquity Edgerouter 4, which I would like to use
as home router and NAS - using OpenBSD 6.5. System setup
went like a breeze, but now I am fighting with openrsync
and USB disks.
With a single large USB disk (Western Digital My Book 8TB)
this would mostly work. openrsync transfers would hang
after several hundred MB, but could be retstarted until
all data was successfully transferred. On some occasions
rsync would crash with SIGSEGV, presumably when ssh process
ran out of memory. Still trying to investigate this.
The real problems started, when I attached an external
RAID disk consisting of 2x 2TB disks in a Fantec QB-X2US3R
disk enclosure. After less than 100MB openrsync would stop
with the following message:
/usr/src/usr.bin/rsync/downloader.c:566: error:
Backup1/home/dev/dev_cc_devel/linux-
2.6.19/..tmp_kallsyms2.o.gS4TUkcuSR: renameat:
Backup1/home/dev/dev_cc_devel/linux-2.6.19/.tmp_kallsyms2.o:
Input/output error
/usr/src/usr.bin/rsync/receiver.c:398: error: rsync_downloader
/usr/src/usr.bin/rsync/client.c:93: error: rsync_receiver
dmesg would show lots and lots of iterations of the same
message:
usb_insert_transfer: xfer=0x9800000000f9bcf0 not free
The system is unable to interact with the harddisk after
this error occurs.
>How-To-Repeat:
Attach USB RAID disk to USB port of Ubiquity Edgerouter 4
running OpenBSD 6.5
disklabel, create BSD 4.2 filesystem across whole disk
start backup with the following command:
openrsync -a -v --no-specials --no-devices
