I've got various RAID 1 & 0 (MDADM) arrays mounted in
/media/ via fstab but I'm coming into trouble creating/deleting files from some of these volumes from the GUI and programs, it's as if they are mount read-only. My default fstab mount options for non home/root arrays is:
UUID="xxx" /media/xxx ext4 noatime,data=writeback,errors=remount-ro 0 1 A typical bootup mount reads as: md6: detected capacity change from 0 to 25999966208 [ 4.112397] md6: unknown partition table [ 4.154724] md: bind<sdc9> [ 4.173584] md/raid1:md18: active with 2 out of 2 mirrors [ 4.173651] md18: detected capacity change from 0 to 80967303168 [ 4.215755] md18: unknown partition table [ 4.303747] md: bind<sdc8> [ 4.335634] md/raid0:md15: md_size is 156249856 sectors. [ 4.335685] md: RAID0 configuration for md15 - 1 zone [ 4.335735] md: zone0=[sdc8/sdd8] [ 4.335876] zone-offset= 0KB, device-offset= 0KB, size= 78124928KB
There's no mention of errors or readonly here in dmesg. I've tried removing the ro option but this makes not difference. What can I try next?
I have added write permissions to the group as a workaround (sudo chmod go+rw /media/xxx) but I'm not sure why this isn't available by default as it would be normally, and perhaps adding these permissions is a security risk.
