Hello list, I have a small rescue system in this box, using /dev/sda3 and /dev/sdb3 in a traditional partition layout. The disks are (supposedly) identical SSDs. All goes well when I boot the system, but by the time I come to write to sdb3 it's dismounted itself. It even dismounted itself once in the middle of syncing portage. Here's a snippet from fstab:
LABEL=RescueSys / ext4 relatime 1 1 LABEL=RescUsrBits /usr-bits ext4 relatime 1 2 I keep the portage tree under /usr-bits. # dmesg | grep sdb3 [ 1.753508] sdb: sdb1 sdb2 sdb3 sdb4 < sdb5 sdb6 sdb7 sdb8 sdb9 > [ 4.833460] EXT4-fs (sdb3): mounted filesystem with ordered data mode. Opts: (null) [ 107.205918] EXT4-fs (sdb3): mounted filesystem with ordered data mode. Opts: (null) You can see the successful mount at 4.8 s; the entry at 107 s is me mounting it again manually. I've rewritten the partition label, and I've run a smartctl test which reported no faults found. I've also just reduced the speed of the chipset, which has three settings: good performance, better performance and turbo. It adopts the turbo setting by default and I've now set it to "better". It's too early yet to see if that will help. What else can I try? -- Rgds Peter
