דיסק קשיח שעובד לאט..

ערב טוב, יש לי בעיה של דיסק איטי:
linux:# hdparm -tT /dev/hdd1 /dev/hdd1: Timing cached reads: 1820 MB in 2.00 seconds = 909.24 MB/sec Timing buffered disk reads: 32 MB in 3.00 seconds = 10.66 MB/sec /dev/sdb1: Timing cached reads: 1808 MB in 2.00 seconds = 903.10 MB/sec Timing buffered disk reads: 136 MB in 3.03 seconds = 44.81 MB/sec​
כפי שאפשר לראות, דיסק אחד איטי באופן משמעותי יותר מהשני. כדי לפסול אפשרויות של udma לא נכון, אז:
linux:/# hdparm -I /dev/hdd1 /dev/hdd1: ATA device, with non-removable media Model Number: WDC WD1200JB-32EVA0 Serial Number: WD-WMAEH1077234 Firmware Revision: 15.05R15 Standards: Supported: 6 5 4 3 Likely used: 6 Configuration: Logical max current cylinders 16383 65535 heads 16 1 sectors/track 63 63 -- CHS current addressable sectors: 4128705 LBA user addressable sectors: 234441648 LBA48 user addressable sectors: 234441648 device size with M = 1024*1024: 114473 MBytes device size with M = 1000*1000: 120034 MBytes (120 GB) Capabilities: LBA, IORDY(can be disabled) bytes avail on r/w long: 74 Queue depth: 1 Standby timer values: spec'd by Standard, with device specific minimum R/W multiple sector transfer: Max = 16 Current = 0 Recommended acoustic management value: 128, current value: 254 DMA: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 udma4 *udma5 Cycle time: min=120ns recommended=120ns PIO: pio0 pio1 pio2 pio3 pio4 Cycle time: no flow control=120ns IORDY flow control=120ns Commands/features: Enabled Supported: * READ BUFFER cmd * WRITE BUFFER cmd * Host Protected Area feature set * Look-ahead * Write cache * Power Management feature set Security Mode feature set * SMART feature set * FLUSH CACHE EXT command * Mandatory FLUSH CACHE command * Device Configuration Overlay feature set * 48-bit Address feature set Automatic Acoustic Management feature set SET MAX security extension * DOWNLOAD MICROCODE cmd * SMART self-test * SMART error logging Security: supported not enabled not locked not frozen not expired: security count not supported: enhanced erase HW reset results: CBLID- above Vih Device num = 1 determined by the jumper Checksum: correct​
חשבתי לפרמט את הדיסק, אבל זו נראית לי גישה לא נכונה. מישהו יכול להמליץ על איזשהו כלי או דרך להעביר את הדיסק הזה טירונות ולראות מה לא בסדר איתו? תודה, אסף

מה נותנת הפקודה

smartctl -a /dev/hdd​
זה קורא את הנתונים של smart מתוך ההארד דיסק ויכולה לתת לך קצת אינדיקציה עליו. רועי

הדיסק האיטי הוא IDE

וכמו כן, הוא Secondary Slave. מספר שאלות: 1. האם יש לו Secondary Master על הערוץ? 2. אם יש, מהו? CD? כונן קשיח אחר? 3. אם יש, בזמן המדידה, מה עומסי הכתיבה/קריאה על ההתקן הנ"ל? תודה.

תשובות

1+2. יש לו secondary master על הערוץ. זה דיסק של WD. דיסק זה עובד תקין:
linux:~# hdparm -tT /dev/hdc1 /dev/hdc1: Timing cached reads: 1816 MB in 2.00 seconds = 907.52 MB/sec Timing buffered disk reads: 136 MB in 3.02 seconds = 44.98 MB/sec​
3. בזמן המדידה המכונה נמצאת במצב מנוחה מוחלט. תודה, אסף

שאלה בוטה

מה קורה כאשר אין לו master? איך הביצועים שלו אז?

תשובה בוטה

ה-Master שיושב איתו על אותו ערוץ הוא חלק מ-Raid 1 של המערכת הפעלה. אני לא הכי שש בעולם לנתק את הדיסק הזה רק כדי לבדוק ביצועים, למרות שאני לא פוסל את המהלך הזה. למען הסר ספק, הדיסק הבעייתי הוא לא חלק משום Raid. אתה רואה איזושהי סיבה הגיונית ש-Slave יתפקד גרוע, אפילו אם ה-Master עובד בצורה תקינה לחלוטין? רעיון אחר: אולי יש דרך לכבות את דיסק ה-Master מבלי להסיר אותו פיזית? זה ייתן את אותה "סביבת בדיקות" שהצעת? (הסרת דיסק ה-Master).
