Hi all, I have a 3 disk RAID0 in my computer. I shutdown the computer to move it, now it won't start back up. I get to the terminal that asks for the root login or CTRL-D to continue. I check
journalctl -p err -b
and I get a bunch of:
blk_update_request: I/O error, dev sdd, sector
ata5.00: exception Emask x0x SAct 0x4000 Serr 0x0 action 0x0
Buffer i/O error on dev md127, logical block, async page read
fsck failed with error code 4
and a few others. After doing some research, I thought that maybe I need to scrub the RAID: https://wiki.archlinux.org/index.php/RAID#Scrubbing. But when I run
echo check > /sys/block/md127/md/sync_action
I get Permission Denied.
How can I fix this with minimal data loss? Please let me know if I can provide more information.
Thanks,

Check the drive cables, you might have dislodged one when moving the computer.

They're all connected. But it makes me think that I could have a bad SATA cable. I'm going to replace them and see what happens. I'll post with updates when I have a moment.
thx

Also I don't believe it's even possible to scrub a RAID0, there are no checksums to scrub against.
Remember that a RAID0 provides no redundancy at all, an error with one drive means losing all of your data. You do have backups right?

I have backups of the important stuff (photos, documents, etc). The RAID is mostly media that can be reproduced (ripped CDs and vinyl). It's not vital if a disk gets hosed. Although if I reconfigure it, I'll do a RAID 1 or something. lol.
