Both machines correctly found that / hadn't been correctly dismounted. After restarting them in single user mode and running 'fsck /' (twice) until the file system was clean, I rebooted them in multi-user mode. One of them needed a while while the /root mirror was rebuilt. Mirrors are managed by gmirror. As they both show similar symptoms I'll concentrate on one server from here. When I run gstat I get: dT: 1.044s w: 1.000s L(q) ops/s r/s kBps ms/r w/s kBps ms/w %busy Name 0 0 0 0 0.0 0 0 0.0 0.0| ada0 0 0 0 0 0.0 0 0 0.0 0.0| ada1 0 0 0 0 0.0 0 0 0.0 0.0| ada2 0 0 0 0 0.0 0 0 0.0 0.0| ada0p1 0 0 0 0 0.0 0 0 0.0 0.0| ada0p2 0 0 0 0 0.0 0 0 0.0 0.0| ada0p3 0 0 0 0 0.0 0 0 0.0 0.0| ada1p1 0 0 0 0 0.0 0 0 0.0 0.0| ada1p2 0 0 0 0 0.0 0 0 0.0 0.0| ada1p3 0 0 0 0 0.0 0 0 0.0 0.0| ada2p1 0 0 0 0 0.0 0 0 0.0 0.0| ada2p2 0 0 0 0 0.0 0 0 0.0 0.0| ada2p3 0 0 0 0 0.0 0 0 0.0 0.0| ufsid/56d1ad46957 f05f1 0 0 0 0 0.0 0 0 0.0 0.0| diskid/DISK-Z3T7P 0J4 0 0 0 0 0.0 0 0 0.0 0.0| mirror/boot 0 0 0 0 0.0 0 0 0.0 0.0| mirror/swap 0 0 0 0 0.0 0 0 0.0 0.0| mirror/root 0 0 0 0 0.0 0 0 0.0 0.0| gptid/41ddec89-70 fc-11e5-89b5-9cb65407dd34 0 0 0 0 0.0 0 0 0.0 0.0| ufsid/561bdc9be2 Previously, the ufsid's, diskid's and gptid's didn't appear in this list and my questions are: Should I be concerned and how do correct this? root@dc1:~ # dmesg | grep ada ada0 at ahcich1 bus 0 scbus1 target 0 lun 0 ada0: ATA8-ACS SATA 3.x device ada0: Serial Number WD-WCATRC668492 ada0: 300.000MB/s transfers (SATA 2.x, UDMA6, PIO 8192bytes) ada0: Command Queueing enabled ada0: 953869MB (1953525168 512 byte sectors) ada0: quirks=0x1<4K> ada0: Previously was known as ad6 ada1 at ahcich2 bus 0 scbus2 target 0 lun 0 ada1: ATA8-ACS SATA 3.x device ada1: Serial Number WD-WCATRC668411 ada1: 300.000MB/s transfers (SATA 2.x, UDMA6, PIO 8192bytes) ada1: Command Queueing enabled ada1: 953869MB (1953525168 512 byte sectors) ada1: quirks=0x1<4K> ada1: Previously was known as ad8 ada2 at ahcich3 bus 0 scbus3 target 0 lun 0 ada2: ATA8-ACS SATA 2.x device ada2: Serial Number Z3T7P0J4 ada2: 300.000MB/s transfers (SATA 2.x, UDMA5, PIO 8192bytes) ada2: Command Queueing enabled ada2: 238475MB (488397168 512 byte sectors) ada2: Previously was known as ad10 Any and all help appreciated, most of my disk knowledge predates ufs2, gptid etc Steve.
